Description

S&S joint purchase method {THE METHOD OF SNS GROUP PURCHASE}

SNS-linked joint purchase method.

These days, joint purchases linked to social media sites are gaining popularity.

SNS is an abbreviation of Social Networking Service, and refers to a service that allows you to establish relationships with unspecified others online. Users build new connections through SNS or reinforce their relationships with existing connections. Representative examples of social media sites are Twitter or Facebook.

When a certain joint purchase site announces that the purchase request for a certain product exceeds a certain amount, a fairly large discount rate is applied to conduct joint purchase, an unspecified number of buyers will receive a specific product through various channels. Participate in joint purchase by acquiring information on publicly announced joint purchases. In particular, when many buyers participate in the joint purchase by encouraging each other to participate in the joint purchase between site members through SNS sites such as Twitter and Facebook, it is also referred to as SNS joint purchase or social commerce.

As a representative example of such a joint purchase site, there is Groupon ( http://www.groupon.com ) in the US and Ticket Monster (http://www.ticketmonster.co.kr/) in Korea. In Korea alone, there are a number of SNS joint purchase sites including Ticket Monster, and all of them can be seen as having entered the joint purchase business after seeing the success of Groupon in the United States.

As the method of proceeding with SNS joint purchase is relatively simple, the entry barrier is very low, so competition between companies is very fierce, and there are many places that close their business accordingly. This is because there is no specific strategy, and all of them are operating almost the same way.

However, there is one major problem with the conventional SNS joint purchase method.

As shown in Fig. 1, the joint purchase is in progress so that only one purchase request price to which one discount rate is applied according to one purchase request quantity section exists.

Buyers who apply for purchase through SNS joint purchase expect to be able to purchase at a discounted price of up to 50%. This is because most of the SNS joint purchase announcements say that if a certain number of purchase requests is requested, it can be traded at a discounted price of about 50%, and such transactions are also made. In fact, the 50% discount has almost no margin. It is a price that makes it difficult to make a profit without a huge volume of trading.

In such a situation, if the joint purchase must proceed so that there is one purchase request quantity section and one purchase request price as in the conventional method, 50% discount is required only when a huge amount of purchase is requested, which is unlikely to be requested. If the seller announces a joint purchase that the seller can trade at the same price, it is likely that buyers will criticize it, so from the seller's point of view, even if a purchase is requested for a large quantity, a 50% discount can be made. It becomes a situation where you have to do it. That is, in the conventional method, an excessive discount rate compared to the quantity requested for purchase is inevitably applied . In such a situation, even if the transaction is concluded because the quantity requested for purchase satisfies the disclosure conditions, the total margin is almost as low as the price with almost no margin (or loss price), which is a 50% discount . No (or lose ) . In other words, the conventional social media-linked joint purchase is not a strategy for a large profit due to separation and multiple purchases, but in most cases, public announcements of joint purchases are made only for the purpose of promoting a business , and a problem in service quality is inevitable. It is a structure, and the seller cannot make frequent joint purchases. And, sellers who sell products that cannot be discounted by 50% without a huge amount or sellers who do not want to sell even at a 50% discount may even think that they will proceed with SNS joint purchase by such a conventional method. It becomes impossible.

Let's look at the problem in more detail through newspaper articles.

In an interview (2011.01.11), the representative of Ticket Monster, the number one social commerce company in Korea, has an indirect problem with social commerce.

“Up to 500 websites (= social commerce companies ) have emerged like a rush. Customer complaints are growing about domestic social commerce services. There are many places that sell poor quality products or close their doors for a short while. From this year, T-Mon will select companies strict and will visit the site and conduct training. From the standpoint of companies, there is also a task that when selling goods through social shopping services, it is necessary to increase the promotional effect as expected. We plan to create a new channel for these traders to communicate directly with customers.”

Looking at the above interviews, only the promotional effect is emphasized, and the many benefits of delamination are not discussed at all. However, in most cases, even the promotional effect is insufficient. This is because there are many cases of crowds or wanderers who only pursue low prices. So, rather, there are many cases of damage that only suffered huge losses.

In addition, KBS'consumer accusation' program evaluated as follows.

" Title: Half price discount coupon, half price service?

Social commerce where you can use products or services at discounted prices through joint purchase through the Internet! A social commerce site that sells various products such as food, performances, beauty, and education first appeared in Korea in March 2010. The social commerce market is growing rapidly, with coupon sales reaching about KRW 60 billion last year. Consumer damage cases are also increasing rapidly. If you visit a company with a discount coupon purchased through social commerce, you will be treated differently from regular customers. Is it true?

A steak specialty restaurant I visited to check. The production crew divided into a discount coupon customer team and a regular customer team and ordered the same menu. At a glance, the plate of the discount coupon customer team looks worse than the general customer team. Not only did the amount of meat vary, but the overall menu was different. In addition, some social commerce companies were requesting unreasonable coupons from service providers. Due to such a lot of discount coupons, consumers are not able to receive proper service.

<Consumer Accusation> has covered the problem of'social commerce' in which services are not properly received due to price discounts."

There is also an article expressing concern at the following Fair Trade Commission due to excessive discounts and operational problems of social commerce companies.

"As the side effects of social commerce were intensifying, the Fair Trade Commission began investigating the damage situation from the 8th. A FTC official said, "We will work out countermeasures after grasping the specific situation with a few companies with scale nationwide." Earlier , in November last year, the FTC issued a consumer damage claim in connection with social commerce ."

In addition, since there are 500 social commerce companies in Korea alone as of January 1, 2011, it is expected that there will be at least 10,000 social commerce companies in the world. It can be said to be the same as Groupon. So, it is said in the media as follows.

"Social commerce rush, lack of strategy is a problem"

"There is a problem that there is no strategy other than preemption."

"If I add my own success factors, I will be able to survive in the market."

In addition, there is an analysis that Groupon is likely to follow the train of eBay, an online auction company. The online coupon business attracted a lot of attention from consumers in the early days, but it is the epitome of Internet service that soon begins to cool down.

In the above circumstances, it is argued that the method of the present application is essential.

Now, as shown in Fig. 1, let's look at in detail the problem of the conventional method of proceeding with joint purchase so that only one purchase request price to which one discount rate is applied according to one purchase request quantity section exists .

For example, as shown in Fig. 2 (or Fig. 4), for a product with a price of 10,000 won, which is not applied at a discount, "150 or more" section, "300 or more" section, "500 or more" Even if you want to proceed with joint purchase so that there are multiple purchase request prices applied with different discount rates for each section,

The joint purchase is proceeding so that only one purchase request quantity section including the “500 or more” section of Fig. 1 and one purchase request price applied with one discount rate.

So, the number of purchase requests for joint purchase was quite large, for example, about 490 as shown in Fig. 5, and there were 350 purchase requests that were satisfied with only the 30% discount rate, not the big discount rate of 50% discount rate. Even though there were quite a few (=40+130+180), all 490 were not satisfied with the lowest quantity to which the discount suggested in the joint purchase announcement such as 500 in Fig. 1 could be applied. There are many cases in which the transaction cannot be concluded.

[Specific Contents for Carrying out the Invention] In the situation in which 490 purchase requests are made as shown in Fig. 5 or 6, which are described in detail as an embodiment of the method of the present invention in the section, one Although the lower limit of the purchase request quantity section of the form in which only the purchase request quantity section exists, 500, the lower limit of the purchase request quantity section, could not be achieved, according to the present method, 350 purchase requests can be purchased. As a result, it is causing too great a loss of opportunity to the buyer or seller.

In the SNS joint purchase, obstacles in the joint purchase process are removed in a reasonable way so that there are multiple purchase request prices applied with different discount rates for each of the plurality of purchase request quantity sections as shown in FIG. 2.

The method according to any one of claims 21 to 28,

In determining the successful bid price,

For each purchase request price, an additional discount is applied from the lowest purchase request price among the purchase request prices corresponding to the cumulative purchase request quantity applied for purchase above the purchase request price and the lower limit quantity of the purchase request quantity section condition. A method characterized in that the successful bid price is determined.

[Sudan Port 30]

The method of claim 29,

A method characterized in that the following method is a method of determining a successful bid price by applying an additional discount.

Successful bid price = A-B

A: Purchase request price in the section where the total purchase request quantity belongs

B: Additional discount amount = C * D/E

In the formula for B above,

C is the number (or a number close to it) obtained by subtracting the purchase request price of the next section of the section to which the total purchase request quantity belongs from the purchase request price in the section to which the total purchase request quantity belongs.

D is the number (or a number close to it) minus the lower limit number of the section to which the total purchase request quantity belongs from the total purchase request quantity.

E is a number (or a number close to it) minus the lower limit of the segment to which the total amount of purchase requests belongs from the lower limit of the segment next to the segment to which the total number of requests for purchase belongs.

(The above numbers are not fixed numbers, but may be numbers that can be arbitrarily adjusted by a person including a seller or site operator.)

In the SNS joint purchase, the joint purchase should be carried out so that there are multiple purchase request prices applied with a specific discount rate for each of the multiple purchase request quantity sections such as the “over 150” section, “over 300” section, and “over 500” section in FIG. What can be done is to solve sellers' long-awaited wishes, and as long as the total quantity requested for purchase is calculated, a reasonable successful bid price can be determined .

At the same time, it is possible to reduce the opportunity loss that has occurred a lot in the past, so that more buyers and more sellers can be satisfied , and transactions can be concluded even at a price with a lower discount rate applied , so that sellers can obtain an appropriate margin. As a result, the quality of products can be improved , and since sellers can frequently make joint purchases, joint purchases, especially SNS-linked joint purchases, can be further promoted.

Even if the joint purchase proceeds to include the section of the purchase request quantity to which no discount is applied, such as the section "less than 150" in FIG. 4, there are many cases in which the buyer or the seller can be satisfied.

The above effects are described in more detail as follows.

If it is possible to disclose joint purchase so that there are multiple purchase application prices applied with a specific discount rate for each of the multiple purchase application quantity sections, as in the present method , only a very large quantity is discounted by 50%, which is a price with little margin. If you announce that you can trade at a price, and that you can trade at a 15 to 30% discount for a quantity that is not very large, the buyer also has a 50% discount for joint purchase. There will be no dissatisfaction, and even if a transaction is concluded because a small amount has been requested for purchase, the successful bid price is determined as the successful bid price with a margin applied with a small discount rate for small amount, so that the seller can see a satisfactory total margin. There will be. So, there will be no abnormalities in quality, and the seller can make frequent joint purchases. From a buyer's point of view, the 30% discounted price and the 50% discounted price appear to be only a 20% difference, but from the perspective of the seller, when considering the margin per unit price, selling at a 30% discount is a 50% discounted price. You may be able to have a margin of ten times that of selling it. So, in Figure 5, if the quantity is 150 or more, a 15% discount, if the quantity is 300 or more, a 30% discount, and if the quantity is 500 or more, a 50% discount. But,

From a seller's point of view, as shown in FIG. 8, if the quantity is more than 150, it is 15% discount, if it is 500 or more, it is 30% discount, and if it is more than 3,000, it is a reasonable configuration. According to the method of the present application, if the seller has a reasonable joint purchase announcement as 15% discount if the quantity is 150 or more, 30% discount if the quantity is 500 or more, and 50% discount if the quantity is 3000 or more, a considerable total Although it is difficult to obtain a margin, and it is difficult to apply for a purchase of 3000 quantities (or from a seller's point of view, as shown in Fig. 9, it is reasonable only to have 15% discount for more than 25 quantities, 30% discount for more than 100 quantities, and 50% discount for more than 500 quantities According to the method of the present application, even if the seller makes a reasonable joint purchase announcement of 15% discount for more than 25 quantity, 30% discount for more than 100 quantity, and 50% discount for more than 500 quantity, even if only 25 or 100 quantity is requested for purchase Although it is difficult to obtain a significant gross margin and 500 quantities are difficult to apply for purchase), even then, a significant gross margin can be obtained and the seller can be satisfied, but as in the conventional method, one purchase according to the period of one purchase request quantity. If there is no choice but to disclose the joint purchase so that only the requested price exists, if it is announced that it will be discounted by 50% for more than 3,000 quantity, it is likely that the transaction will not be concluded because the quantity requested for purchase of that amount is not applied for purchase. , Since the seller announces joint purchase that the product can be traded at 50% discount if the quantity is more than 500, because the seller will be criticized by buyers for only publicizing it for promotional purposes rather than for sale, 500 quantity is requested to be purchased and 50% discounted. Even if a transaction is made at a price, there is not much margin from the seller's point of view, so it is difficult for the seller to be satisfied in terms of margin, and in many cases, only a promotional effect can be expected due to exposure to popular joint purchasing sites. And, in fact, most of the publicity effects are insufficient. This is because they are often crowds who only pursue low prices.

And, although it is still active that only products in the service field are distributed through the social commerce method, the method of the present application can be used to activate the joint purchase of industrial products as well.

In fact, there are very few industrial products that can be sold at a discount rate of about 50%, as industrial products cost a lot of material and often have a low margin.

In such a case, as in the method of the present application, various kinds of industrial products can be distributed through social commerce only when discount rates of several levels are presented.

In addition, even if the purchase request quantity section is changed, the price does not change or the price change is extremely small, so that the purchase request benefit is corresponding for each purchase request quantity section, the purchaser's point of view It will not be a factor of choosing whether to choose the application benefits, so products with a paid price are useful, but the price is free from the beginning, such as insurance subscription, internet subscription, and mobile phone subscription products, making it more useful for products that only require a contract. For sellers, you can make it more profitable in terms of margins.

In addition, since the variable cost is included in all the amounts referred to herein, or is additionally calculated automatically or as necessary in the procedure, the variable cost should be considered to be actually considered or to be considered even if it is not mentioned individually. If stated individually, this is not the case because the sentences of the present application are rather messy and may interfere with understanding the core of the present application.

19. Variable benefits: As a concept including variable costs, variable costs mean that the amount fluctuates only in terms of amount, but variable benefits mean that benefits vary in terms of benefits including services as well as amounts.

In addition, since the variable benefits are included in all the benefits mentioned herein, or are additionally calculated automatically or as necessary in the procedure, even if the variable benefits are not mentioned individually, they should be considered as actually being considered or should be considered. If stated individually, this is not the case because the sentences of the present application are rather messy and may interfere with understanding the core of the present application. Or, I will insert a phrase about the variable benefit in parentheses by saying'(in consideration of the variable benefit)' so that the sentence does not pay much attention to such a phrase.

20. Refund: This means returning part or all of the amount paid in advance, including refund.

********** End of term definition.

In order to facilitate understanding of the present application, it will be described from the examples.

An example is given of a service product called food, but it is obvious that industrial products are also possible.

At some restaurants, steak A is usually sold for 10,000 won.

By the way, suppose that a joint purchase event was held for a stake named A at a joint purchase site, and the joint purchase was announced while placing the joint purchase conditions as shown in Fig. 4.

Assume that many buyers apply for a joint purchase after reviewing the conditions for joint purchase as shown in FIG. 4.

When applying for purchase for joint purchase by the method according to the present application,

Each buyer thinks that they will apply for purchase, expressing their intention to fulfill the purchase at a certain price, and expressing their own purchase request price and number of purchase requests.

(Of course, when each buyer applies for purchase, it is also possible to apply for purchase by saying that they will purchase two or more products.)

The purchase request price from a buyer's point of view is the maximum price that the purchaser can accept.

For example, requesting a purchase at a purchase price of 7,000 won

If the successful bid price exceeds 7,000 won, I will not purchase.

He expressed his intention to fulfill the purchase as long as the successful bid price is less than 7,000 won.

And, while applying for purchase, even though the successful bid price has not yet been determined, for each purchaser, the purchase cost reflecting the expressed purchase request price is paid.

There are various payment methods. Examples of payment methods include deposits, reserves, various points, credit cards, account transfers, and mobile phone payments. There are various ways of refunding accordingly. In addition, since such a payment system can be easily implemented by an ordinary e-commerce technician, it will not be described in detail.

If, at the time of the joint purchase announcement as shown in FIG. 4, it is assumed that the result of the purchase request is as shown in FIG.

It should be noted that the quantity of products expressed as numbers below also includes the quantity of countless service products including beauty salon services and nail care services. For example, even if the number of services is expressed as a number, it will not be unreasonable to understand the method of the present application.

Although the following embodiments have been described mainly using the number of persons, it will be apparent to anyone that the same principle is applied to the product requiring the number of persons or the number of times, and thus, a detailed description will not be made for it.

To explain Fig. 5,

A total of 490 products were applied for purchase through joint purchase, and among those 490 products,

There were 40 purchase requests at the purchase price of 10,000 won,

There were 130 purchase requests at the purchase price of 8,500 won,

There were 180 purchase requests at the purchase price of 7,000 won,

At the purchase price of 5,000 won, it can be seen that there were 140 purchase requests.

Regardless of the number, it is unconditionally possible to purchase at 10,000 won, which is a price that does not apply any discount, which is the usual price, so the “satisfaction” column in the “less than 150” row in the “purchase request quantity section” column is “satisfied”,

(To be more specific,

If it is less than 150, it is announced that it will be supplied at the usual price of 10,000 won. The cumulative total of the number of purchase requests at the purchase price of 10,000 won is 40, and the lower limit of the “purchase request quantity section” in that row is, in fact, 1 Since it is a dog, it can be seen that the transaction can be concluded at the usual price, so the “Satisfaction” column in the “less than 150” row in the “Purchase Request Quantity Section” column is “Satisfied”.)

If it is more than 150, it is announced that it will be supplied at 8,500 won, the price applied with a 15% discount. However, the cumulative total of the number of items requested for purchase with a purchase request price of 8,500 won or more is 170, and the lower limit of the “purchase request quantity section” in that row is Since there are 150, it can be seen that the transaction can be concluded with a 15% discount. So, the “Satisfaction” column in the “Over 150 (=150~299)” column in the “Purchase Request Quantity Section” column is “Satisfied” "ego,

If it is more than 300, it is announced that it will be supplied at a price of 7,000 won, a 30% discount applied. The cumulative total of the number of items requested for purchase with a purchase request price of 7,000 won or more is 350, and the lower limit of the “purchase request quantity section” in that row is 300 Since it is a dog, it can be seen that the transaction can be concluded even with a 30% discount price, so the “Satisfaction” column in the “300 or more (=300~499)” column in the “Purchase Request Quantity Section” column is “Satisfied” ego,

If it is 500 or more, it is announced that it will be supplied at a price of 5,000 won, with a 50% discount applied, but the cumulative total of the number of purchase requests at a purchase request price of 5,000 won or more is 490, the lower limit of the “purchase request quantity section” in that row. Since it is less than 500, it can be seen that the transaction cannot be concluded with a 50% discount. So, the “Satisfaction” column in the “500 or more” row of the “Purchase Request Quantity Section” column is “Unsatisfied”.

In the state described so far, there can be two methods of determining the successful bid price.

Method 1 is,

For each purchase request price, a purchase request corresponding to a section in which the cumulative purchase request quantity requested for purchase above the purchase request price is greater than the lower limit quantity of the purchase request quantity section condition (where the successful bid price can be determined by the purchase request price) The lowest purchase request price among the prices is determined as the successful bid price .

(In this way, in the end) 7,000 won, which is the lowest price among 10,000 won, 8,500 won, and 7,000 won, which corresponds to the purchase request quantity section in which the “satisfaction” field is “satisfied” becomes the successful bid price.

In addition, 350 items, the cumulative total of all the numbers applied for purchase with a purchase price of 7,000 won or more, which is the successful bid price, can be traded at the same price of 7,000 won.

In other words,

Buyers who apply for purchase at the purchase price of 10,000 won will be able to purchase for 7,000 won,

Buyers who apply for purchase at the purchase price of 8,500 won will be able to purchase for 7,000 won.

Of course, the purchaser who applied for purchase at the purchase request price of 7,000 won will be able to purchase it for 7,000 won.

I will express that the word becomes available for purchase as the pass of the purchase application and that the purchase is concluded, but all mean the same.

In addition, 140 items applied for purchase with a purchase request price of 5,000 won, which is less than the successful bid price of 7,000 won, become impossible to purchase. I would say that the word becomes impossible to purchase is expressed as failing the purchase application, and also expressed that the purchase cannot be concluded, but all mean the same.

And, when making a purchase request, before the successful bid price for each purchaser is determined, the amount obtained by multiplying the purchase request price for each purchaser by the number of purchase requests has been paid in advance for the purchase price reflecting the purchase request price.

The purchaser who becomes unable to purchase can be refunded all the amount paid in advance when he/she applies for purchase, and the product can not be supplied.

The purchaser who has become available for purchase can be supplied with the product by refunding the amount paid in advance when he/she applies for purchase, minus the purchase cost reflecting the successful bid price (= winning bid price times the number of purchase requests).

To explain in more detail,

When applying for purchase at a purchase request price of 5,000 won, which is lower than the successful bid price of 7,000 won, the purchaser who applied for purchase for 140 items for which 5,000 won each was paid in advance is refunded to the purchaser who paid in advance, and the product is not supplied. .Because it is not possible to purchase by applying for a purchase at a price lower than the successful bid price, so the entire amount paid in advance is refunded.

A cost that is the same as the successful bid price of 7,000 won, which is the difference between the pre-paid amount of 7,000 won per item and the successful bid price of 7,000 per item for the purchaser who applied for purchase for 180 items for which 7,000 won was paid in advance while applying for purchase. The product is supplied with a refund of 0 won per person. In other words, the difference between the successful bid price and the amount paid in advance is refunded, which means that there is no refund.

For 130 items for which 8,500 won was paid in advance while applying for purchase at a purchase price of 8,500 won, which is higher than the successful bid price of 7,000 won, the purchaser who applied for purchase was 8,5000 won per unit and the successful bid price 7,000 per item. The product is supplied with a refund of 1,500 won per unit, which is the difference between the two.

For 40 items for which 10,000 won each was paid in advance while applying for purchase at a purchase request price of 10,000 won, which is higher than the successful bid price of 7,000 won, the amount paid in advance is 10,000 won per item and the successful bid price of 7,000 per item. The product is supplied with a refund of 3,000 won for each difference cost.

The second method is a slightly improved method of the first method,

For each purchase request price, the cumulative purchase request quantity applied for purchase above the purchase request price, the purchase corresponding to the section larger than the lower limit quantity of the purchase request quantity section condition (where the successful bid price can be determined by the purchase request price) This is a method in which a specific price is determined as the successful bid price among the prices below the lowest purchase request price among the applied prices.

To put it simply, it is a method in which an additional discount can be applied from the successful bid price by the first method.

As for the additional discount method, a great variety of methods can be devised, i.e., an infinite number of methods.

As for the additional discount limit, the price after the additional discount is equal to or greater than the purchase request price corresponding to the next purchase request quantity section of the section in which the successful bid price by the first method belongs (to the side with the larger purchase request quantity). Recommended. In the following example, it means that it is recommended that the price after additional discount is 5,000 won or more. (If, in the section to which the successful bid price by the first method belongs (to the side with the larger number of requests), the next purchase request quantity section If there is no, for example, if the total number of purchase requests in FIG. 5 is 500 or more, there may be no additional discount, or a separate additional discount method may be applied.)

To explain one of the various ways in which additional discounts are applied by way of example,

According to the first method, a 30% discount is applied for 300 or 499 items,

According to the second method here, a 30% discount is applied to 300, and a 49% (about) discount is applied to 490.

So, even if a buyer applies for purchase for 7,000 won, if the total number of purchase requests becomes 490, it is discounted by 49% (about 5,100 won) so that the successful bid price is about 5,100 won.

To explain in more detail,

Successful bid price = A-B = 7,000-1,900=5,100 won

In the above winning bid price calculation formula,

A is the purchase request price (=7,000 won) in the section where the total number of purchase applications (490) belongs,

B is the additional discount amount (1,900 = 2,000 X 190/200).

In the formula for B above,

2,000 is the number of subtracting the purchase request price of 5,000 won in the next section (to the side with the larger number of purchase requests) in the section where 490 items belong to the purchase request price of 7,000 won.

190 is the total number of purchase requests (490) minus 300, the lower limit of the section in which 490 items belong.

200 is a number minus 300, the lower limit of the section to which 490 silver items belong, from 500, which is the lower limit of the next section of the section to which the total number of purchase requests (490 items) belongs.

A person of ordinary skill in the art or a person skilled in the art will be able to easily come up with another additional discount method different from the additional discount method of the above embodiment, so that another method will not be listed any more.

(However, to introduce another additional discount method,

Among co-purchasers, customers who apply for purchase in large quantities (e.g., 20) will have the successful bid price determined at a certain amount or an additional discounted price above a certain percentage from the purchase request price corresponding to the section including the total purchase request quantity. May be

The successful bid price may be determined as the purchase request price corresponding to the next section in which the purchase request quantity is larger than the section in which the total purchase request quantity is included.

However, if the additional discount rate in this way is too large, the effect of the discount effect may be lowered even by joint purchase with unspecified people. (A 5% additional discount is recommended, and up to 10% additional discount is required. In any case, additional discounts can be differentially given depending on the level of contribution.)

When applying for purchases in large quantities, it is possible to apply for purchase with the ID of one specific person, but each purchaser can express themselves as a person who promotes joint purchase with a purchaser of a certain ID.

If the seller allows, the purchase price that is not possible with the current cumulative purchase request quantity, for each purchase request price, the cumulative purchase request quantity that has been requested for purchase above the purchase request price, and the purchase that can be determined by the purchase request price The successful bid price may be determined even at a price equal to or less than the purchase request price corresponding to a section smaller than the lower limit quantity of the application quantity section condition.

And, Facebook, an American social network company, has already provided a promotional feature that informs my friends that I paid with Facebook credits and gives me a discount if my friends make a purchase again. You can also give discounts in a similar way.)

In the second method here as well, if, before the successful bid price is determined for each buyer, when applying for purchase, the purchase price that is the amount of the purchase request price multiplied by the number of purchase requests was paid in advance, so

The purchaser who becomes unable to purchase can be refunded all the amount paid in advance when he/she applies for purchase, and the product can not be supplied.

The purchaser who becomes available for purchase can be prevented from being supplied by refunding the amount paid in advance when he/she applies for purchase, minus the purchase cost (= winning bid price times the number of purchase requests) reflecting the successful bid price.

To explain in more detail,

When applying for purchase at a purchase request price of 5,000 won, which is lower than the successful bid price of 5,100 won by the second successful bid price determination method, the purchaser who applied for purchase is refunded 5,000 won for each pre-paid item for 140 items for which 5,000 won each was paid in advance. The product is not supplied because it is not possible to purchase by applying for a purchase at a price lower than the successful bid price, so the entire amount paid in advance is refunded.

At the purchase request price of 7,000 won, for 180 items for which 7,000 won was paid in advance while applying for purchase, a refund of 1,900 won per item, which is the difference between the pre-paid amount of 7,000 won and the successful bid price of 5,100 As a result, goods are supplied.

For 130 items for which 8,500 won each was paid in advance while applying for purchase at a purchase request price of 8,500 won, which is higher than the successful bid price of 5,100 won, the purchaser who applied for purchase is 8,5000 won and the successful bid price of 5,100 each The product is supplied with a refund of 3,400 won per unit, which is the difference between the two.

For 40 items for which 10,000 won each has been paid in advance while applying for purchase at a purchase price of 10,000 won, which is higher than the successful bid price of 5,100 won, the amount paid in advance is 10,000 won per item and 5,100 won per item. The product is supplied with a refund of 4,900 won for each difference cost.

When a joint purchase proceeds with methods that can be derived from the method of the present application including the method of the above embodiment with the method of determining the successful bid price according to the first method and the second method as described above,

Because purchases are often possible for buyers who are satisfied with a small discount rate, the opportunity loss for buyers and sellers is reduced.

If, as in the past, there is a sale announcement that the product will be supplied at a 50% discount only when 500 or more products are requested for purchase, there will be no purchaser who can purchase even though 490 products are requested.

According to the method of the present application, 350 of the 490 requested for purchase can be traded, so it can be seen that the conventional method has a large but large loss of opportunity for buyers and sellers compared to the method of the present application.

In addition, even though a purchase request is made at the purchase request price of an amount higher than the successful bid price, the purchaser can purchase at the same price as the successful bid price. There is no need to apply for purchase only at the purchase price.

For example, a buyer who is satisfied with the 15% discounted price may apply for a purchase at the 15% discounted purchase price, but the successful bid price may be determined at the discounted amount by 30% or 50% (or other discount rate). You will be able to apply for purchase while expecting. If the amount discounted by 30% or 50% (or other discount rate) is determined as the successful bid price, the amount discounted by 30% or 50% (or other discount rate) even though the purchase request is made at the purchase request price of 15% discount This is because it becomes available for purchase.

Even if there is no discount, a buyer who is satisfied with the price without any discount, who is willing to purchase anyway, applies for purchase at the purchase request price of the price at which there is no discount, but maybe 15% or 30% or 50% (or other discount rate) is discounted. It is possible to apply for purchase in anticipation that the successful bid price may be determined at the price. If the amount discounted by 15% or 30% or 50% (or other discount rate) is determined as the successful bid price, you may apply for a purchase price of 15% or 30% or 50% (or other discount rate) This is because) becomes available for purchase at a discounted amount.

In the end, when applying for a joint purchase by the method of our company, all you have to do is apply for purchase at a price with a discount rate that is roughly satisfactory, and there is a strong will to never purchase unless the price is applied with a very high discount rate. Only the buyer can apply for purchase at a very low price with a very high discount rate applied.

Buyers themselves will be able to focus more on public relations to attract more buyers.

And, as shown in Fig. 6 below, “dissatisfaction” occurs in the section where the number of purchase requests is “150 or more”, but even if “satisfaction” occurs in the section where the number of purchasers is “300 or more”, the “satisfaction” column is “ It is not necessary to explain that the purchase price of 7,000 won for the section with “300 or more”, which is the lowest price among the purchase request price corresponding to the “satisfied” purchase request quantity section, becomes the successful bid price.

At the initial point of applying the method of the present application, joint purchase has been carried out so that only one purchase request quantity section and the purchase request price correspond, but suddenly too many purchase request quantity sections due to the good effect of the present application. If it exists, buyers may not readily accept it or cause confusion,

First of all, it is recommended to proceed with the joint purchase so that there are two purchase request quantity sections as shown in FIG. 21, and it is recommended to gradually increase the purchase request quantity section.

This is because, compared to a situation where only one purchase request quantity section exists, only two purchase request quantity sections can exert a tremendous effect.

For reference, at the time of purchase request, each purchaser does not express his or her own purchase request price and quantity of purchase request that he will carry out the purchase at a certain price.

Proceed with joint purchase so that there are multiple purchase request prices applied with different discount rates for each number of purchase requests, such as the “150 or more” section, “300 or more” section, and “500 or more” section in Fig. 2 (or Fig. 4). I will explain that I cannot .

Assume that a number of purchasers have acquired the disclosure information on the joint purchase process as shown in FIG. 2, and that a total of 470 purchase requests are requested as shown in FIG.

Each buyer, if the bid price at the time of purchase application as long decided how much of the price or less without representations hagetdaneun fulfill Buy, That is, each buyer from a variety of purchase application rates in the joint purchase information disclosed, including two self It is assumed that a purchase application is made , hoping that a large number of purchase requests will be requested by many buyers without selecting a satisfactory purchase price .

Then, a problem arises that the selling price cannot be determined even though the total number of purchase requests has been calculated after the joint purchase application is closed. Let's find out why.

The total number of purchase requests, 470, belongs to the “300 or more (=300~499)” range of purchase requests in the joint purchase announcement, so the successful bid price is 7,000 won per unit applied with a 30% discount rate. There is no problem when the transaction is completely concluded after the payment is made in won, but it cannot.

This is because the psychological state of each purchaser who has applied for purchase of 470 may be as shown in FIG. 3. (Fig. 3 does not show that buyers actually applied for purchase while selecting their respective purchase request price, but only the psychological state at the time of purchase application.)

Looking at Figure 3, out of 470, which is the total number of purchase requests, 180 were applied for purchase with the price of 5,000 won per item applied with a 50% discount rate in mind. As the successful bid price was determined at 7,000 won per item, the quantity of 180 purchase requests This purchase is expected to be cancelled.

Since each purchaser did not select their own purchase request price at the time of purchase request, in the actual situation, since the seller or each purchaser does not know that they analyzed the psychological state as shown in Fig. 3, when and how much quantity will be canceled. I don't know. It can be seen only after the deadline for expressing each buyer's intention on whether to make a purchase at a successful bid price of 7,000 won or cancel the purchase.

As the deadline for expressing intention has passed, the quantity of 180 purchase requests applied for purchase with the purchase request price of 5,000 won in mind has been canceled, and the remaining quantity becomes 290 (=470-180), and 290 are announced joint purchase. Since it belongs to the “over 150 (=150~299)” range of purchase requests, the successful bid price will be re-adjusted to 8,500 won with a 15% discount.

(However, some buyers are often unacceptable for the rebalancing of the successful bid price. Because, as some buyers think, the winning bid price should be 7,000 won because the number of 470 purchase requests is in the first place anyway. However, from a seller's point of view, with the remaining purchase request quantity of 290, the successful bid price should be 8,500 won (the successful bid price becomes 7,000 won), and the margin is too small to sell at 7,000 won increments. Or, it is judged that there is a possibility of loss, so there are too many cases where this joint purchase becomes something that did not exist.)

And, (although it is virtually very difficult to overcome this situation in online purchases that have to be made quickly, even if agreements are reached to overcome this situation)

The purchaser who applied for the purchase of the quantity of 290 pieces should try to collect the expressions of each purchaser's intention on whether to make a purchase at a successful bid price of 8,500 won or cancel the purchase.

It is, in fact, impossible to know each buyer's will once again like this, but anyway, once the deadline for expressing once again passed,

Of the 290 purchase requests, a successful bid price of 8,500 won was accepted for 140 purchase requests with a purchase request price of 8,500 won in mind from the beginning, and the 150 purchased with the purchase request price of 7,000 won in mind. Since the number of purchase requests is canceled, the remaining quantity becomes 140 (=290-150), and 140 do not belong to the section of “150 or more (=150-299)” in the joint purchase announcement. There are too many cases where they refuse to sell even at the 8,500 won with a 15% discount rate applied. Thus, as shown in FIG. 2, there are many cases where it is impossible to publicize joint purchase so that there are a number of sections of the purchase application quantity.

In Fig. 2, since there are three purchase application quantity sections presented by the seller, it is only necessary to collect the expressions of each buyer's intention for the initial successful bid price or the changed successful bid price twice, but it is virtually impossible to collect opinions twice like this. If a joint purchase announcement is made so that the number of purchase request quantity sections exists, the more the number of purchase request quantity sections increases, the more times the number of times to converge the expression of intention increases. It becomes impossible to do.

In this way, as shown in Fig. 2, a joint purchase announcement is made so that a number of purchase application quantity sections are included, and in the method of recklessly applying for purchase without selecting a purchase application price at a level that each purchaser is satisfied with at the time of purchase application,

It is virtually impossible to collect expressions of intention to each purchaser on whether to sign a purchase at the original or changed bid price or cancel the purchase over several times.In addition, a successful bid performed by each purchaser for the purpose of guaranteeing purchase intention Even before the price is decided, it is completely unthinkable that each buyer pays in advance the cost reflecting the purchase request price, which is the maximum amount they can pay for the purchase of the product, or a purchase deposit.

For reference, when each purchaser applies for a joint purchase, each purchaser expresses his willingness to be satisfied with a certain price, and explains the reason why the joint purchase is possible only if payment is made for that price'before the successful bid price is determined'. I'll find out.

At first glance, there seems to be no difference between paying as much as the successful bid price after the successful bid price is determined, or before the successful bid price is determined, and it seems that it is easier to pay after the successful bid price is determined, but that way, joint purchase can proceed. There is not.

From the point of view of the buyer, you may be puzzled that you are paying a satisfactory level before the successful bid price is decided.

From the seller's point of view,

Among the buyers who applied for joint purchase after the successful bid price is determined, the probability of a buyer who does not pay among the buyers who signed the purchase

Before the successful bid price is determined, i.e., when applying for a joint purchase, after each purchaser pays a price that is satisfactory to him or her, the probability of a buyer canceling the payment among the purchasers who signed a purchase among the purchasers who applied for the joint purchase

Because it is much larger.

In other words, there is a case in which the purchase intention decreases between the time when the joint purchase request is made and the time when the successful bid price is determined, or it is annoying to visit the site again to make payment, or because the payment deadline is missed and payment cannot be made. To happen a lot because of.

From the buyer's point of view

It is also quite annoying to visit the site once again and make payment after the successful bid price is determined.

Buyers who participated in joint purchases even a little by looking at the high discount rate are very likely to avoid payment.

However, if the payment was made at the time of participation in the purchase, the probability of canceling the payment made anyway is relatively low.

The e-commerce system 10 for implementing the joint purchase method according to the present invention includes one or more purchase application terminals 12 that can be used by an unspecified number of purchasers for purchase applications, or (mainly one person (or one company)). It includes a sales application terminal (18), or a joint purchase server 16 operating an online site on which joint purchase is conducted, or a network communication network 14 including the Internet for communication.

(In entering sales information,

The site operator may receive sales information from the seller, and the site operator may input sales information through a terminal used by the site operator, or the seller may directly input sales information through a sales application terminal used by the seller.

If the seller directly inputs sales information through the sales application terminal used by the seller, the sales application terminal 18 used by the seller may be required. If the site operator receives the sales information from the seller and inputs the sales information through the sales application terminal used by the site operator, it may be said that the sales application terminal 18 used by the site operator is necessary. Anyway, it can be said that the sales application terminal is necessary.)

The purchase application terminal 12 accesses the joint purchase server 16 to check the joint purchase progress information, and when the purchaser wants to purchase a specific product through joint purchase, enter his or her purchase application information or It is a client terminal used to receive purchase progress information.

The sales application terminal 18 is a client terminal used for a seller to access the joint purchase server 16, input his or her joint purchase condition information, and check the joint purchase progress information.

If the joint purchase conditions are entered in such a way that the site operator directly enters the joint purchase conditions information after the site operator receives the contents of the joint purchase conditions from the seller, it may not necessarily require a sales application terminal used by the seller. However, if the terminal of the site operator is regarded as a sales application terminal, it can also be said that the sales application terminal 18 is necessary.

The joint purchase server 16 operates an e-commerce site based on the joint purchase method, provides joint purchase progress information, receives and stores purchase application information from the purchase application terminal 12, and stores the purchase request information. ), the public purchase information (or sales information) is received and stored, and the joint purchase process is processed.

In addition, since the joint purchase method according to the present invention includes a process in which the joint purchase server 16 receives and refunds the amount in advance from the buyer or seller, the joint purchase server 16 includes a separate payment server (not shown) and It may be interlocked or implemented to perform a payment function on its own, and the joint purchase server 16 may be interlocked with a separate sales server (not shown) to provide information on sales products.

Such an e-commerce system 10 is very similar to a conventional e-commerce system for a general social commerce joint purchase shopping mall, an Internet shopping mall, and an Internet auction site, and the present invention differs from the prior art only in the method of operating joint purchase. It is only necessary to change the operating program provided on the joint purchase server 16 side, and those skilled in the art will be able to smoothly implement the present invention within the scope of the conventional e-commerce system construction technology even if the Guji system is not described in more detail.

The joint purchase method according to the present invention is a joint purchase method in an e-commerce transaction in which a seller (mainly, one person) and one or more (mostly many) purchasers can participate in the same product at the same time. (A) Apply for purchase by entering the purchase request information including the purchase request price corresponding to the maximum price that the person can pay for the product to be purchased within the available purchase application time and the purchase request quantity, which is the quantity of the product desired to be purchased.

Through the joint purchase server, the purchase application status including the purchase application quantity for each purchase application price or the cumulative purchase application quantity for each purchase application price applied for purchase above each purchase application price is aggregated through the joint purchase server,

After the joint purchase application is terminated, through the joint purchase server,

For each purchase request price, the purchase request price corresponding to the section where the cumulative purchase request quantity applied for purchase above the purchase request price is greater than the lower limit of the purchase request quantity section condition (the successful bid price can be determined by the purchase request price) Among the prices below the lowest purchase request price, the specific price is determined as the successful bid price,

The result of the transaction, including the purchaser who applied with the purchase request price equal to or greater than the successful bid price, is determined as the purchaser who signed the purchase, and the purchaser who applied for the purchase application price less than the successful bid price, is determined as the purchaser who was not able to conclude the purchase. It is provided or notified to the connected terminal including the sales application terminal.

Therefore, different from the conventional joint purchase method, even though there is a purchaser who has signed a purchase, a purchaser who is determined to be a purchaser who has not made a media purchase may occur .

The purchaser can guarantee his/her purchase request by entering the purchase request information including the purchase request price and the purchase request quantity, and paying part or all of the purchase cost in advance. (16) is the purchaser's purchase by returning part or all of the amount received in advance in the form of a purchase cancellation penalty to the purchaser who cancels the purchase request after the successful bid price is determined, Seller's loss due to cancellation can be compensated.

In this way, all purchasers who have applied for purchase can be guaranteed to execute the purchase.

Of course, the joint purchase server 16 immediately refunds the amount received in advance when the purchaser who paid in advance is determined to be a purchaser who has not concluded a purchase according to the result of the joint purchase in the future, while the purchaser who paid in advance is converted to a purchaser If it is determined, the amount received in advance is replaced with the purchase cost of the product, but the difference cost paid in advance beyond the purchase cost reflecting the successful bid price is calculated and refunded.

In addition, if the seller also pays a predetermined sales deposit in advance and cancels the sale or does not smoothly deliver the product to the buyer even after the successful bid price is determined, the joint purchase server 16 returns and purchases the sales deposit received in advance. By providing to the signed buyers, the loss of the buyer due to the seller's cancellation of the sale can be preserved, and the reliability of the transaction can be secured.

In addition, according to the present invention, the joint purchase server 16 does not close a transaction at the purchase request price requested by each purchaser, and all purchasers determined as purchase contracted purchasers can purchase the product at the same price as the successful bid price. Therefore, it is possible to satisfy multiple buyers as much as possible with one joint purchase. (It is possible to prevent even one unhappy buyer .)

In this regard, the joint purchase server 16 basically receives the purchase cost calculated in consideration of the purchase application price and the number of purchase applications requested by each purchaser before the successful bid price is determined (mainly at the time of purchase application). Therefore, the difference between the purchase cost previously paid by each purchaser and the purchase cost reflecting the successful bid price at the time after the purchase contract is determined is calculated and refunded for each purchaser immediately.

The joint purchase method according to the present invention consists of the following steps (or means).

(A step (or means) of transmitting public purchase announcement information, including that the purchase request price corresponding to each of two or more purchase request quantity sections, to the joint purchase server;)

-In this step (or means), as shown in Fig. 4, the seller establishes the conditions for joint purchase, including the correspondence of different purchase request prices to which different discount rates may be applied for each of two or more different purchase request quantity sections for a specific product. Is a step (or means) that is provided to the site operator and input by the site operator or directly input by the seller.

It is self-evident that different purchase application prices are considered to be corresponding even though different purchase application prices are not corresponded to different purchase order quantity sections in the joint purchase announcement, and a specific discount rate is matched to different normal prices. It belongs to the scope of rights. This is because a discounted price is derived when a discount rate is applied to the usual price.

Through the joint purchase server, the purchase application terminal provides information on the joint purchase announcement including that the purchase request price (to which a specific discount rate may be applied) is matched for each of two or more purchase application quantity sections for the product to be traded. (Or the sales application terminal: SS ?) To the connected terminal including Accepted Step (or means)

-In this step (or means), as shown in Fig. 4, the seller establishes the conditions for joint purchase, including the correspondence of different purchase request prices to which different discount rates may be applied for each of two or more different purchase request quantity sections for a specific product. This is the step (or means) of providing the site operator to the site operator so that the joint purchase announcement information entered by the site operator or directly entered by the seller can be displayed on the purchase application terminal.

When a specific discount rate is applied for each of two or more purchase request quantity sections, it is recommended that different discount rates be used for each purchase request quantity section, but joint purchases may be conducted so that the same discount rate is applied if necessary even in different sections.

And, a specific discount rate may be 0%. In other words, there may be a section of the number of purchase requests to which the normal price is applied.

One of the two or more purchase request prices is selected and entered from the purchase application terminal used by each purchaser, or the number of purchase requests is Entered The purchase application information including the information is entered and transmitted to the joint purchase server. (Become and store on the joint purchase server: SS ?) Step (or means)

-In this step (or means), after connecting to the joint purchase server 16 through the purchase application terminal 12 used by each purchaser, the joint purchase disclosure information on the products for sale provided by the joint purchase server 16 is provided. If you want to purchase through joint purchase by selecting a specific product after checking, if you enter the purchase request information including the purchase request price and the number of purchase requests within the available time of purchase request, the corresponding purchase request information will be sent to the joint purchase server. It can be transmitted and stored to the (16) side.

At this time, each purchaser may directly input the purchase request price he or she desires, or among a plurality of purchase request prices provided by the joint purchase server 16 as in the example description through FIG. 4 or 5 above. You can also select any one and enter it.

There are a variety of optional input methods, including inputting the provided purchase request price number one by one or by clicking a button related to the provided purchase request price number.

Selecting and inputting any one has been described in detail with an example of FIG. 4 or 5 above, so the description will end with this level.

In addition, if the number of requests for purchase is one, the number of requests for purchase may be automatically processed as one, even if the number of requests for purchase is not separately input. That is, for a specific purchase request quantity including the case where the purchase request quantity is 1, the purchase request quantity may be automatically input and processed even if the purchase request quantity is not separately input.

In addition, each purchaser may be operated so that the purchase request price for which he/she applied for purchase can be changed until the successful bid price is determined. As an example of how to change, you can change it by simply selecting a new purchase request price, or cancel a previous purchase request and apply for a new purchase at a new purchase request price. If payment was made in advance at the time of purchase request, additional payment or refund may be made according to the changed price settlement rule.

Part of the purchase cost reflecting the purchase request price before the successful bid price is determined, including when the purchase request information is transmitted from each purchase request terminal through the above joint purchase server Or at the cost of all purchases Payments for which are accepted in advance (taking into account variable costs) Step (or means) 3

-In this step (or means), when each buyer applies for purchase, he/she guarantees his/her purchase application by pre-paying all or part of the purchase price according to the purchase request price and quantity of purchase request (in consideration of the variable cost). It is a step (or means) to do.

If the purchaser does not pay the purchase cost in advance before the successful bid price is determined (mainly at the time of purchase application), the purchase request may be canceled later without any restrictions and cause damage to the seller. In the case of cancellation, payment is received in advance in order to receive a partial refund in the form of a purchase cancellation penalty or to strongly express a purchase intention.

Through the joint purchase server, the purchase application status including the number of purchase requests for each purchase request price or the cumulative purchase request quantity for each purchase request price that is higher than the purchase request price is displayed on the joint purchase server. Step (or means) aggregated through

-In this step (or means), the joint purchase server 16 counts the purchase request status for the purchase request quantity for each purchase request price or the cumulative purchase request quantity for each purchase request price that is applied for purchase above each purchase request price or to provide.

Here, the cumulative purchase request quantity for each purchase request price refers to the total quantity of all the purchase request quantities applied for purchase at a price higher than the corresponding purchase request price.

For example, the joint purchase server 16 may provide a purchase application status including the cumulative purchase application quantity displayed in the "cumulative" column of FIG. 5.

That is, the "cumulative total" of FIG. 5 or 6 represents the cumulative number of purchase requests for each purchase request price that has been applied for purchase above each purchase request price.

For each purchase request price, the cumulative accumulated purchase request quantity applied for purchase above the purchase request price corresponds to a section larger than the lower limit quantity of the purchase request quantity section condition (where the successful bid price can be determined by the purchase request price) As the successful bid price is determined at a price (a specific price among the prices) below the lowest purchase request price among the requested purchase price,

The purchaser (at least one of the purchasers) who has applied for purchase at a purchase request price equal to or higher than the successful bid price is determined as the purchased purchaser, and the purchased purchaser can purchase at the same price as the above winning bid price, and the purchase request price less than the successful bid price. The purchaser (at least one of the purchasers) who has applied for purchase The result of the transaction, including the decision to be an unsuccessful purchaser, is derived, and the purchase application terminal (Or the sales application terminal: SS ?) Provided or notified to the connected terminal including (or means)

-This step (or means) is a step (or means) in which the successful bid price is determined according to the end of the joint purchase application deadline, and the result of the transaction is concluded, including the division into the purchased buyer and the non-purchased buyer.

(Thus, unlike the conventional joint purchase method, there may be a purchaser who cannot purchase a purchase even though there is a purchaser who has signed a purchase even though it is a joint purchase.)

The description of this step (or means) has been described in detail with the example of FIG. 5 above, and thus will not be described in detail.

Of course, part or all of the purchasers who could not be purchased at the discretion of the site operator, the seller's discretion, or a separate remedy are recognized or relieved as purchased purchasers, and thus part of the purchase application quantity requested by the recognized or relieved purchaser. Alternatively, the entire purchase can be signed or partial cost support can be provided.

The step (or method) to be explained later, if the purchase cost (mainly reflecting the desired purchase price) paid in advance by the buyer at the time of purchase application is greater than the purchase cost reflecting the successful bid price, the difference (or method) In the same context as saying that after the refund amount is calculated, it may be possible to refund more than the refund amount calculated at the discretion of the site operator or the seller.

After the successful bid price is determined,

Through the joint purchase server,

The pre-paid purchase cost (above) received from the purchase application terminal used by the purchaser determined as the purchaser who has not concluded the purchase is refunded (in consideration of the variable cost),

The step in which the difference (above) paid in advance in excess of the purchase cost reflecting the successful bid price among the pre-paid purchase costs accepted from the purchase application terminal used by the purchaser determined as the purchaser concluded (considering the variable cost) is refunded (Or means); Step 4-1 (or means)

-In this step (or means), the joint purchase server 16 refunds all purchase costs (or more) previously paid by the purchaser who was not determined as the purchaser who signed the purchase after the joint purchase was terminated (in consideration of the variable cost), and purchase This is the step (or means) of refunding (in consideration of the variable cost) the previously paid cost (or more) in excess of the purchase cost reflecting the successful bid price among the purchase costs previously paid by the signed buyer.

That is, the final selling price is determined as the successful bid price, and the purchaser initially calculates the purchase cost reflecting the purchase request price, subtracts the purchase cost reflecting the successful bid price from the amount previously paid, and refunds the rest.

It's hardly possible, but at someone's discretion, they could give you more refunds than the'rest' amount above. That's why they said that they would refund'more than' the cost of the difference. In addition, the word'abnormal' in the refund of other expenses in different parts of the present application is also used with the same intention.

In addition, since the present invention does not apply for a patent on a method of refunding some amount of the amount paid by card, that is, it is not a patent application for electronic payment among the patent fields related to e-commerce, the problem to be solved in the present invention I think it is not,

To mention reimbursing the amount paid in advance by card,

In other words, to mention a few ways to refund the amount (or more) of the amount (or more) by subtracting the purchase cost reflecting the successful bid price from the amount paid in advance to the buyer who paid in advance for the amount exceeding the purchase cost reflecting the successful bid price with a card. It looks like this (other methods are possible).

1. Automated payment of purchase costs that have already been (carded) payments canceled and new successful bid prices reflected.

2. Charge the amount paid in advance on the card invoice in a positive amount, and charge the difference (= amount equal to the amount paid in advance minus the purchase cost reflecting the successful bid price) in a negative amount. As a result, the successful bid price It is summarized by paying the reflected purchase cost (currently, if there is a price change when the airline changes the reservation, it is handled in this way.)

3. The credit card company remits the difference between the customer's bankbook

4. Remittance of the amount that the seller paid in advance to the customer's bankbook minus the purchase cost reflecting the successful bid price (the seller bears the loss of card fee)

It is a step (or means) that compensates the seller's losses and guarantees the reliability of the transaction by redeeming it (in consideration of the variable cost) and providing it to the seller.

In other words, from the point of view of the seller, all buyers who applied for purchase were determined to be sure to purchase if they were determined to be purchasers, and they applied for sale by lowering the selling price as much as possible through the calculation of the profits of the peeled polymorphism. If canceled, even if the product is sold after receiving a successful bid, the profit may be much lower than originally thought or damage may occur. Therefore, a predetermined penalty is given to the buyer who cancels the purchase request.

Furthermore, the joint purchase method according to the present invention may further include the following steps (or means).

Step 1-1 in which the payment for the sales deposit is accepted in advance (in consideration of the variable cost) before the successful bid price, including the time when the sales information is transmitted (from the sales application terminal) through the joint purchase server, is determined. Or means).

It is to secure.

After the purchaser concluded with the purchase is derived,

The seller accepts the cancellation of the sale from the sale application terminal used by the seller through the above joint purchase server, or the seller assumes the obligation according to the sales right granted to the seller. To fulfill If the information that it did not fail is accepted, the sales deposit paid in advance will be returned (in consideration of the variable cost) or

Step (or means) of refunding the sales deposit (or more) to the seller (in consideration of the variable cost) when a normal transaction is made

-As described above, in this step (or means), if the seller cancels the sale without a justifiable reason or does not perform product provision smoothly, the seller returns the bid deposit previously paid in order to compensate the loss of the buyers who signed the purchase. It is a step (or means).

In addition, the following two steps (or means) may be further added.

After the successful bid price is determined through the joint purchase server,

Payment for the total purchase cost compared to the purchase cost reflecting the successful bid price is accepted from the purchase application terminal used by the purchaser determined as a new purchaser or a purchaser who has not signed a purchase (in consideration of the variable cost) or

The purchase cost in which the previously paid purchase cost (in consideration of the variable cost) received from the purchase application terminal used by the purchaser who was determined as a purchaser who could not conclude the purchase due to the purchase request price less than the above-mentioned purchase price is reflected in the winning price Including that payment for insufficient purchase cost is accepted (in consideration of variable costs) from the purchase application terminal used by the purchaser who is determined to be the purchaser who has not signed the purchase.

-This step (or means) is a step (or means) in which a purchaser who has not signed a purchase or a new purchaser is given an additional opportunity to purchase the product at the successful bid price because a purchase request is made at a purchase price less than the successful bid price. .

(If more opportunities are given,

-New buyers can pay the purchase cost reflecting the successful bid price,

-An additional step (or means) of paying the insufficiently paid amount by the buyer, who is determined as a buyer who has not made a purchase, is further required.

That is, the amount paid by the buyer in advance

In the case of less than the successful bid price multiplied by the number of purchase orders ordered at the time of purchase request by the purchaser determined as the purchaser who has not concluded the purchase

This is to enable the acquisition of sufficient information for the appropriate successful bid sales price prediction, and therefore, among the buyers who have always tried to purchase at an appropriate price line, the buyer who fails to purchase as a result of applying for purchase at a purchase request price that is too low due to insufficient information. Minimize the number.

Until now, in fact, the general concept of the present application has been described as a concept that may belong to the embodiment of the concept asserted in the present application so that it is easy to understand.

From now on, the general concept of the present application will be described.

The information on the joint purchase announcement to which the comprehensive concept of the present application is applied contains the content that more benefits are given to the purchaser as the number of purchase requests increases. These benefits include none at all. This is because it may not provide benefits if it is less than a certain number of purchase requests.

Until now, the method of the present application was described only with the benefit of lowering the price among the benefits. That is, as shown in FIG. 4, FIG. 5, or 6, it was described as an example only when there was a public announcement of a joint purchase by a seller that the price decreased as the number of purchase applications increased.

From the buyer's point of view, the benefit is not just that the price is lowered.

In addition to decreasing the price as the number of purchase requests increases,

As the number of purchase requests increases, the condition that various products (= goods or services) are added to the purchaser (including changes to more valuable products) and supplied to the purchaser in addition to the basic product is also a benefit from the viewpoint of the purchaser.

Even when the number of purchase requests increases, the price remains the same, but as the number of purchase requests increases, various products (= goods or services) are added to the buyer (including changes to more valuable products) and supplied. Conditions are also a benefit from the buyer's point of view. If the price is the same, it includes the case where it is free.

As above, if the price is left as it is (or slightly lowered), and more products are added to the buyer (including changes to more valuable products), the buyer's point of view is that more products of some value are added (as a more valuable product). Changes are included), but in the seller's position, it is more profitable than the price discount from the seller's point of view because it is only necessary to spend a small amount more than when converting any value received by the buyer into an amount.

For example, rather than selling a meat with a price of 10,000 won at a discount of 4,000 won and selling it for 6,000 won, it is often more profitable for a seller to leave the price at 10,000 won and give an additional 4,000 won. Because the cost of meat worth 4,000 won may be only 1,000 won, it is a profit of 3,000 won from the seller's point of view than selling at a discount of 4,000 won. At the same time, there will be many cases where the buyer is also satisfied.

As the number of purchase requests increases, some products other than basic products are added (including changes to more valuable products), and the types of products supplied to buyers are very diverse. It is up to the seller to decide. For example, the following products may be additionally given.

Gift certificate (e.g. 10,000 won, 50,000 won, 100,000 won), cash refund (e.g. 10,000 won, 50,000 won, 100,000 won), service time (e.g. 10 minutes, 30 minutes, 1 hour), service period (e.g. 1 Months, 6 months, 1 year), discount rate (e.g. 10%, 30%, 50%), exemption from specific amounts (e.g.: KRW 10,000 out of 30,000 KRW, KRW 20,000 exempt from 30,000 KRW, 3 out of 30,000 KRW Exemption from 10,000 won), products (eg cell phone hooks, stylus pens, LCD protective film), products (eg beverages, tea, wine), etc.

If the additional product is "cash refund", it means that the seller can give cash to the buyer.

4 and 5 are charts showing the results of the joint purchase announcement and purchase request, in which the price decreases as the number of purchase requests increases for the stake A, which has a normal price of 10,000 won.

However, as shown in Fig. 10, depending on the seller, the price does not change even if the purchase request quantity increases, and as the purchase request quantity increases, a certain product is added to the buyer (or includes changes to a more valuable product) to be supplied. (In order to reduce the number of drawings, information and results of the joint purchase announcement were expressed at once.)

Referring to FIG. 10, as follows.

Even if the number of purchase requests increases, the price remains the same at 10,000 won. However, as the number of purchase requests increases,

In section 2 (purchase application quantity), only beverages are additionally supplied,

In section 3 (purchase application quantity), additional drinks and tea are supplied,

In section 4 (purchase application quantity), it can be seen that it was announced that additional beverages, tea and wine will be supplied.

(if not,

In section 2 (purchase application quantity), only beverages are additionally supplied,

In section 3 (purchase application quantity), only cars are additionally supplied,

It can be said that in section 4 (purchase application quantity), only wine will be additionally supplied. In the table showing the joint purchase announcement information as shown in FIG. 10, there will be no confusion if the announcement of the joint purchase announcement is made about how to interpret the additional supply product for each purchase request quantity section.

In this table, additional products are displayed.

When there are no overlapping benefits in the purchase application benefit column corresponding to each purchase quantity section as shown in Fig. 10,

In section 2 (purchase application quantity), only beverages are additionally supplied,

In section 3 (purchase application quantity), additional drinks and tea are supplied,

In section 4 (Purchase Request Quantity), the method of interpreting that beverages, tea, and wine are additionally supplied will be referred to as the'cumulative benefit application method' in the method of applying additional benefits.

In section 2 (purchase application quantity), only beverages are additionally supplied,

In section 3 (purchase application quantity), only cars are additionally supplied,

In section 4 (purchase request quantity), the method of interpreting that only wine is additionally supplied will be referred to as the'individual benefit application method' in the additional benefit application method.

As shown in Fig. 11, if the benefits are repeatedly indicated in the purchase application benefit column corresponding to each purchase quantity section, there will be no confusion even if there is no notice on the interpretation of the chart.

(Sections 2 and 3 in Fig. 11 are marked with the redundant benefit of adding drinks, and sections 3 and 4 are marked with the redundant benefit of adding drinks and tea)

11, it would be safe to interpret it as follows unless there are specific conditions.

In section 2 (purchase application quantity), only beverages are additionally supplied,

In section 3 (purchase application quantity), only drinks and tea are additionally supplied,

Drinks, tea, and wine are additionally supplied in section 4 (purchase application quantity))

Here, mainly, the description will be continued on the assumption that it is notified that an additional supply product will be configured as in FIG. 11 when a joint purchase announcement is made as in FIG. 10.

Looking at the result portion of FIG. 10, the total number of purchase requests became 490, and it can be seen that the purchase request benefit corresponding to the third section was successful based on the same principle as the explanation principle related to FIG. 5. In other words, if the price of the successful bid is 10,000 won, and the information on the joint purchase announcement that the additional benefit application method is applied as the "cumulative benefit application method" is notified in the joint purchase disclosure information, the additional product supplied will be the difference between beverages and beverages (depending on the seller). If, in the joint purchase announcement information, that the additional benefit application method is applied as the "individual benefit application method", the rule of supplying only additional car may be applied.).

In addition, the purchaser who applied for purchase while selecting the purchase application benefit corresponding to the 1st, 2nd, or 3rd (purchase request quantity) section at the time of purchase request will purchase with the benefit condition corresponding to the 3rd (purchase request quantity) section It is concluded, and the purchaser who applied for purchase while selecting the purchase application benefit corresponding to section 4 (purchase application quantity) at the time of purchase application is not signed for purchase. This purchase signing principle was discussed in detail in the description related to FIG. 5.

However, to explain in more detail once again,

In the result part of Fig. 10, the total number of purchase applications was 490,

Looking at the purchase application status, once it was notified in the joint purchase disclosure information that the method of applying additional benefits is applied as the "cumulative benefit application method",

The number of purchase applications for which the purchase application benefit without additional products is selected for 10,000 won is 40, the cumulative total is 40,

130, the cumulative total of 170,

The number of purchase applications selected for the purchase application benefit of 10,000 won plus drinks and tea is 180, the cumulative amount is 350,

For 10,000 won, the number of applications for purchase is 140, and the cumulative total is 490.

(If, in the joint purchase disclosure information, it is notified that the method of applying additional benefits is applied as the "individual benefit application method",

The number of purchase applications for which the purchase application benefit without additional products is selected for 10,000 won is 40, the cumulative total is 40,

130, the cumulative total of 170,

The number of purchase applications for which the purchase application benefit is an additional product of 10,000 won is 180, and the cumulative total is 350,

For 10,000 won, the number of applications for purchase is 140, and the cumulative total is 490.)

Since the lower limit of the condition for the number of purchase requests for sections 1, 2 and 3 is smaller than the cumulative total of the number of requests for purchases, the "Satisfaction" column in the areas 1, 2 and 3 is "Satisfied". Among the purchase application benefits corresponding to the "satisfaction" field in the "satisfied" field, the purchase application benefit price for section 3, which is the best purchase application benefit, is 10,000 won. If it is notified in the joint purchase disclosure information that it is applied as ", the purchase application benefit for which beverages and tea are additional products will be successful, and the purchase application was made while selecting the purchase application benefit for the 1st, 2nd, or 3rd section. The cumulative number of purchases, which is the cumulative number of purchases made by the signed purchaser, is 350, and additional drinks and tea are supplied to the purchaser at a price of 10,000 won.

(If, depending on the seller, the additional benefit application method is notified in the joint purchase disclosure information that the “individual benefit application method” is applied, the additional product will be supplied only with the difference.)

Since the lower limit (500 items) of the conditions for the purchase order quantity section of section 4 is larger than the cumulative purchase quantity (490 items), section 4 is due to the “satisfaction” column of section 4 being “unsatisfied” The product cannot be supplied with the purchase application benefit of 10,000 won and additional supply of beverages, tea, and wine. So, if the purchase was applied by selecting the product to be supplied additionally while paying 10,000 won in advance at the time of purchase, the purchaser who could not conclude the purchase due to the selection of the purchase application benefit under the condition of section 4 is 10,000 You just need to refund each won.

Since the process of reaching the above conclusion has been dealt with in detail in the description of FIG. 5, further detailed descriptions are omitted.

For reference, Fig. 5 may be represented as Fig. 22, but the meanings of Figs. 5 and 22 are the same.

12 shows an example of selling an oven.

As shown in FIG. 12, even if the number of purchase requests increases, the price remains unchanged to KRW 500,000, as shown in FIG. 10, and it is disclosed that more products are supplied (including changes to more valuable products) as the number of purchase requests increases. .

In the result part of Fig. 12, the total number of purchase applications was 490,

It can be seen that the purchase application benefit corresponding to section 3 has been awarded by the same principle as in FIG. 5 or 10. In other words, the price of the winning bid is 500,000 won,

If the information on the joint purchase announcement that the method of applying the additional benefits is applied as the "how to apply the cumulative benefits" is notified, the additional products will be scales and pans. (Depending on the seller, the method of applying the additional benefits will be referred to as the "How to apply individual benefits". "If the joint purchase announcement informs us that it applies to ", the rule of supplying only additional frying pans may be applied.).

In addition, the purchaser who applied for purchase while selecting the purchase application benefit corresponding to the 1st, 2nd, or 3rd (purchase request quantity) section at the time of the purchase request is the purchase application benefit condition corresponding to the 3rd (purchase request quantity) section When the purchase is applied, the purchaser who applies for purchase while selecting the purchase application benefit corresponding to section 4 (purchase request quantity) is not signed. This purchase signing principle was dealt with in detail in the description related to FIG. 5 or 10.

Now, let's look at an example where the price is free and more products are added (including changes to more valuable products) as the number of purchase requests increases.

This is primarily an example that can be used for service contracts, such as Internet subscriptions and insurance subscription products. When subscribing to these services, there is no cost at the time of subscription, but it can be applied to products with a fixed cost at regular intervals (eg, every month).

I will explain with an example of Internet subscription products.

Among the products of an internet network supplier called KT, there is a high-speed internet product that requires payment of 30,000 won per month. However, if you sign up with a contract to continue using it for more than 3 years, you only have to pay 25,000 won per month. From the buyer's point of view, money is not required in most cases in the name of the subscription fee. (It is possible to announce a joint purchase so that a fee for the first month is paid in advance, but in this embodiment, it is assumed that it is not.)

13 is an example showing the announcement and result of joint purchase for KT, broadband internet, 25,000 won/month, 3-year contract product subscription.

As shown in Fig. 10, even if the number of purchase requests increases, the price remains unchanged (to 0 won (= free)), and as the number of purchase requests increases, more products supplied (including changes to more valuable products) are added. .

13, the total number of purchase applications was 490,

It can be seen that the purchase application benefit corresponding to section 3 has been awarded by the same principle as in FIG. 5 or 10. In other words, if the price of the successful bid is 0 won (= free), and the additional benefit application method is applied as a "cumulative benefit application method" in the joint purchase announcement information, the additional product will be supplied with a mouse and MP3. (Depending on the seller, if the joint purchase announcement information that the additional benefit application method is applied as the "individual benefit application method" is notified in the joint purchase disclosure information, the rule of providing only MP3 additionally may be applied.) At the same time, the buyer who has signed a purchase can pay 25,000 won per month.

In addition, the purchaser who applied for purchase while selecting the purchase application benefit corresponding to the 1st, 2nd, or 3rd (purchase request quantity) section at the time of purchase request will purchase with the benefit condition corresponding to the 3rd (purchase request quantity) section It is concluded, and the purchaser who applied for purchase while selecting the purchase application benefit corresponding to section 4 (purchase application quantity) at the time of purchase application is not signed for purchase. This purchase signing principle was dealt with in detail in the description related to FIG. 5 or 10.

Also, let's see if the benefit is cash.

When a seller gives a buyer a cash benefit, literally, the seller gives the buyer cash.

Fig. 19 is an example showing the announcement and results of joint purchase for KT, high-speed Internet, 25,000 won per month, 3-year contract product subscription.

As shown in Fig. 10, even when the number of purchase requests increases, the price does not change (to 0 won (= free)), and as the number of purchase requests increases, more products are supplied (including changes to more valuable products). .

In the result section of Fig. 19, the total number of purchase applications was 490,

It can be seen that the purchase application benefit corresponding to section 3 has been awarded by the same principle as in FIG. 5 or 10. In other words, if the price of the successful bid is 0 won (= free) and the additional benefit application method is applied as the "cumulative benefit application method" in the joint purchase announcement information, an additional cash 60,000 won (= 10,000 won + 2) 10,000 won + 30,000 won) will be deposited to the buyer. (Depending on the seller, if the joint purchase announcement information that the additional benefit application method is applied as the "individual benefit application method" is notified in the joint purchase disclosure information, the rule of supplying only 30,000 won additionally will be applied. May be). At the same time, the buyer who has signed a purchase can pay 25,000 won per month.

In addition, the purchaser who applied for purchase while selecting the purchase application benefit corresponding to the 1st, 2nd, or 3rd (purchase request quantity) section at the time of the purchase request is the purchase application benefit condition corresponding to the 3rd (purchase request quantity) section The purchase is concluded as a result, and the purchaser who applied for purchase while selecting the benefit corresponding to section 4 (purchase application quantity) at the time of purchase application is not signed. This purchase signing principle was dealt with in detail in the description related to FIG. 5 or 10.

Also, let's look at the case where the unit of the purchase request quantity is an amount.

For example, as shown in Fig. 14, a certain bakery intends to promote a joint purchase of several types of bread.

In order to purchase several types (or one type or all types) that are subject to joint purchase at the price at the time the buyer visits and purchases the bread, the number of purchase applications requested for joint purchase (= As the purchase request amount) increases, the discount rate to the price at the time the purchaser visits and purchases may correspond (not the price at the time when the purchaser visits and purchases, but the price at the time when the joint purchase is announced). )

In this case, when the purchaser applies for purchase, the purchaser can apply for purchase by expressing his intention to purchase some amount of bread.

In doing so, looking at the results of the purchase request (of many buyers) in FIG. 14,

Since the unit of the purchase request quantity is 10,000 won, the total purchase request quantity becomes 4.9 million won, and it can be seen that the purchase request benefit corresponding to the third section was successful based on the same principle as in FIG. 5 or 10. In other words, if the information of the joint purchase announcement that the additional benefit application method is applied as the "cumulative benefit application method" is notified in the successful bid, each purchaser who passes the purchase request is the amount of bread that is expressed in order to purchase. 45% (=0%+15%+30%) discount. (Depending on the seller, if an additional benefit application method is applied as a “individual benefit application method” in the joint purchase disclosure information, , You may apply the rule that you can only purchase at a 30% discount).

In addition, the purchaser who applied for purchase while selecting the purchase application benefit corresponding to the 1st, 2nd, or 3rd (purchase request quantity) section at the time of the purchase request is the purchase application benefit condition corresponding to the 3rd (purchase request quantity) section When the purchase is applied, the purchaser who applies for purchase while selecting the purchase application benefit corresponding to section 4 (purchase request quantity) is not signed. This purchase signing principle was dealt with in detail in the description related to FIG. 5 or 10.

This is a condition in which each buyer who has signed a purchase can actually purchase the amount of bread for the amount requested for purchase at a discounted percentage price corresponding to the successful bid benefit.

Even if you pay in advance for the amount requested for purchase based on the price at the time the joint purchase is announced before the successful bid benefits are determined, no refund may occur.

After the successful bid benefit is determined, in the case of purchase based on the price at the time the purchaser visits and makes the purchase, the payment cannot be made in advance, so a refund may not occur.

This method may be more suitable for products with short periods of price fluctuations and tight margins. For example, car gasoline.

15 will be described as an example.

As shown in Fig. 14, the unit of the purchase request quantity in Fig. 15 is also an amount.

For example, as shown in Fig. 15, a gas station intends to promote joint purchase of several types of oil.

In order to purchase several types (or one type or all types) that are subject to joint purchase at the price at the time the buyer visits and purchases the oil, the number of purchase requests applied for joint purchase (= As the purchase request amount) increases, the discount rate to the price at the time the purchaser visits and purchases may correspond (not the price at the time when the purchaser visits and purchases, but the price at the time when the joint purchase is announced). )

In this case, when the purchaser applies for purchase, he or she can apply for purchase by expressing his intention to purchase some amount of oil.

In doing so, looking at the results of the purchase request (of a number of buyers) in FIG. 15,

Since the unit of the purchase request quantity is 10,000 won, the total purchase request quantity becomes 4.9 million won, and it can be seen that the purchase request benefit corresponding to the third section was successful based on the same principle as in FIG. 5 or 10.

In other words, if the information for the joint purchase announcement that the additional benefit application method is applied as the "cumulative benefit application method" is notified in the successful bid, each purchaser who passes the purchase request will receive gasoline equivalent to the amount expressed intent to purchase while applying for purchase. 3% (=0%+1%+2%) discounted amount will be available. (Depending on the seller, if an additional benefit application method is applied as a "individual benefit application method" in the joint purchase disclosure information, , You can also apply the rule that you can purchase at a 2% discount).

In addition, the purchaser who applied for purchase while selecting the purchase application benefit corresponding to the 1st, 2nd, or 3rd (purchase request quantity) section at the time of the purchase request is the purchase application benefit condition corresponding to the 3rd (purchase request quantity) section When the purchase is applied, the purchaser who applies for purchase while selecting the purchase application benefit corresponding to section 4 (purchase request quantity) is not signed. This purchase signing principle was dealt with in detail in the description related to FIG. 5 or 10.

This is a condition in which each buyer who has signed a purchase can actually purchase the amount of oil for the amount requested for purchase at a discounted percentage price corresponding to the successful bid benefit.

Even if you pay in advance for the amount requested for purchase based on the price at the time the joint purchase is announced before the successful bid benefits are determined, no refund may occur.

After the successful bid benefit is determined, in the case of purchase based on the price at the time the purchaser visits and makes the purchase, the payment cannot be made in advance, so a refund may not occur.

In the case of gasoline, the unit of purchase request quantity may be liters.

Fig. 16 will be described as an example.

Since the unit of the purchase request quantity is liters, the total purchase request quantity becomes 490 liters, and it can be seen that the purchase request benefit corresponding to section 3 has been awarded by the same principle as in FIG. 5 or 10. In other words, the volume that each purchaser who passed the purchase request expressed intention to purchase while applying for purchase, if it was notified in the joint purchase disclosure that the additional benefit application method was applied as a "cumulative benefit application method". L) gasoline will be able to be purchased at a 3% (=0%+1%+2%) discount. (Depending on the seller, the method of applying additional benefits is applied as a "individual benefit application method". If notified in the public information, the rule to purchase at a 2% discount may apply).

In addition, the purchaser who applied for purchase while selecting the purchase application benefit corresponding to the 1st, 2nd, or 3rd (purchase request quantity) section at the time of the purchase request is the purchase application benefit condition corresponding to the 3rd (purchase request quantity) section When the purchase is applied, the purchaser who applies for purchase while selecting the purchase application benefit corresponding to section 4 (purchase request quantity) is not signed. This purchase signing principle was dealt with in detail in the description related to FIG. 5 or 10.

This is a condition that allows each purchaser to actually purchase gasoline for the volume requested for purchase at the price per liter of discounted percentage corresponding to the successful bid benefit.

If payment is made in advance before the successful bid benefit is determined, the amount of the price per liter of the discounted percentage requested for purchase by the requested volume, multiplied by the price per liter of the discounted percentage corresponding to the winning bid, multiplied by the requested volume Subtracted difference costs will be refunded.

Before the successful bid benefit is determined, in the case of paying in advance for the amount requested for purchase based on the price at the time the joint purchase is announced, a discount corresponding to the successful bid benefit from the price per liter of the discounted percentage requested by the person (Refer to the Refund section in Fig. 16-Assuming that the price per liter is 100 won when there is no discount),

After the successful bid benefit is determined, in the case of purchase based on the price at the time the purchaser visits and makes the purchase, the payment cannot be made in advance, so a refund may not occur (not shown).

Now, let's look at an example in which an additional benefit includes a benefit with an extended period.

When promoting a joint purchase of a 6-month aerobics course product, there may be a joint purchase announcement and result as shown in FIG.

17, it can be seen that the total number of purchase applications was 490, and according to the same principle as in FIG. 5 or 10, the purchase application benefit corresponding to section 3 was successful. In other words, if the price of the successful bid is KRW 300,000, and the information on the joint purchase announcement that the additional benefit application method is applied as the "cumulative benefit application method" is notified in the joint purchase disclosure information, the additional product will be extended by 1 month and extended by 2 months. It will be extended by 3 months. In other words, as the basic 6-month course ticket is extended by 3 months (= None + 1 month + 2 months), you can receive a total of 9 months. (Depending on the seller, the method of applying additional benefits is referred to as "How to apply individual benefits" If it is notified in the joint purchase disclosure information that it is applied as an application, the rule of providing an additional 2 month extension may be applied.)

And, until now, as the number of purchase applications increased

There is no added product, but the price is lowered

While the price does not change, only the added product is accumulated or only the benefits are changed to a more valuable product.

As the price is lowered as shown in FIG. 18, additional products may be accumulated or replaced with more valuable products.

18 is an example of public announcement of joint purchase of subscription products and results thereof.

It is assumed that the product is contracted to use a service for two years, which requires a service charge of 50,000 won per month as a basic fee, while purchasing a specific mobile phone and moving the mobile phone service company to a specific mobile phone.

As you purchase a mobile phone in the first section of the purchase request quantity section, you will have to pay 300,000 won for the mobile phone (it may be free if it is old, but it is the latest mobile phone). (For reference, you can change the rate plan or period of use at will. If there is, it is expensive at around 700,000 won for the above specific mobile phone.)

When the number is changed from No. 1 to No. 2, the mobile phone price does not change, but a mobile phone ring worth 10,000 won is additionally supplied.

When the 2nd to 3rd section is changed, the mobile phone cost is also lowered by 10,000 won, and additional products are added (or changed) from a mobile phone ring worth 10,000 won to a stylus pen worth 20,000 won.

When changing from section 3 to section 4, the mobile phone cost is lowered by 10,000 won, but there are no additional products.

In the result part of Fig. 18, the total number of purchase applications was 490,

It can be seen that the purchase application benefit corresponding to section 3 has been awarded by the same principle as in FIG. 5 or 10. In other words, if the price of the mobile phone is 290,000 won and the additional benefit application method is applied as the "cumulative benefit application method" in the joint purchase announcement information, the additional product will be supplied with a mobile phone ring equivalent to KRW 10,000 and 2 It is a stylus pen worth 10,000 won. (Depending on the seller, if the joint purchase announcement information that the additional benefit application method is applied as a "individual benefit application method", the mobile phone price is 290,000 won and only a stylus pen worth 20,000 won is added. You may apply the rules you supply). And, a purchaser who has signed a purchase sign up for a service that uses a plan with a basic fee of 50,000 won per month for two years.

Now, let's look at the complex benefits that are added or changed as the number of purchase requests increases. Various benefits including the addition or change of cash, gift certificates, discount rates, or general industrial products may be combined, but in the following embodiment, more cash and general industrial products are added (changed to more valuable products) as the number of purchase requests increases. Also included) will be described in the embodiment as supplied.

Figure 20 is an example showing the announcement and results of joint purchase for KT, high-speed Internet, 25,000 won per month, 3-year contract product subscription. (Refer to the description related to Figure 13 for detailed product descriptions)

As shown in FIG. 10, even if the purchase request quantity increases, the price does not change to 0 won (= free), and as the purchase request quantity increases, more products to be supplied (including changes to more valuable products) are added.

In the result part of Fig. 20, the total number of purchase applications was 490,

It can be seen that the benefit corresponding to section 3 has been successful based on the same principle as in FIG. 5 or 10. In other words, if the price of the successful bid is 0 won (= free) and the additional benefit application method is applied as the "cumulative benefit application method" in the joint purchase announcement information, an additional cash 60,000 won (= 10,000 won + 2) 10,000 won + 30,000 won) and a mouse equivalent to 10,000 won and MP3 equivalent to 50,000 won will be supplied to the buyer. (Depending on the seller, if the joint purchase announcement information that the additional benefit application method is applied as the "individual benefit application method" , It is also possible to apply an additional supply of only 30,000 won in cash and MP3 (worth 50,000 won)). At the same time, the buyer who has signed a purchase can pay 25,000 won per month.

In addition, the purchaser who applied for purchase while selecting the purchase application benefit corresponding to the 1st, 2nd, or 3rd (purchase request quantity) section at the time of the purchase request is the purchase application benefit condition corresponding to the 3rd (purchase request quantity) section When the purchase is applied, the purchaser who applies for purchase while selecting the purchase application benefit corresponding to section 4 (purchase request quantity) is not signed. This purchase signing principle was dealt with in detail in the description related to FIG. 5 or 10.

During the description using FIGS. 10 to 21 as an example, in order to facilitate understanding of the description of the benefits, the elements of the benefits are divided into a purchase request price (or discount rate) and an additional supply product. The purchase request price is an amount that may be enforced for the purchaser to compulsory payment at the time of purchase request as a condition of fulfillment of the seller's obligations after the purchase is signed. I just let go. The discount rate may be the discount rate for the amount that the buyer must deposit when applying for purchase, or it may be the amount that the buyer can receive when the actual product is delivered.Therefore, the discount rate should be written in the column where the items to be fulfilled by the buyer are indicated. It may be efficient, or it may be more efficient if it is written in the column where the seller has to do something.

Anyway, the factors related to the benefits,

In a state where the details of benefits, including expressing what the buyer should do and what the seller should do, so that the buyer can clearly understand,

It may be indicated in the same column at once, or it may be indicated by dividing the notifier arbitrarily. In the case of dividing it, it is also possible to divide it into two or more elements, including the purchase request price (or discount rate) and the additional supply product.

Now, let's synthesize the contents we want to pursue comprehensively in this application.

Detailed description of each step (or means) below will be omitted. This is because, in a transaction in which only the price is lowered as the purchase request quantity increases, the key points of the following techniques have been described in great detail, particularly in the description of FIG. 5. The difference is not an important matter, and it can be understood by analogy sufficiently from the preceding explanation.

And, including the process of paying and refunding the purchase cost in advance, the process of paying and refunding the purchase deposit, and the process of paying and refunding the sales deposit.

As described in the transaction where only the price decreases as the number of purchase requests increases, techniques not described in the following may also be applied. Since it has been described in detail in the description related to FIG. 5, the application method will not be described separately.

In the following description of the claim, the word "purchase request price" was replaced with the word "purchase application benefit" in the explanation of how to receive the benefit of lowering only the price as the number of purchase requests increases. The meaning of "application price" was replaced with the meaning of "the following purchase application benefits", and the meaning of "less than the purchase application price" was replaced with the meaning of "excessive purchase application benefits". This is because the purchase application price and the purchase application benefit are in inverse proportion to each other. For example, the higher the purchase price, the lower the purchase application benefit, and the lower the purchase application price, the higher the purchase application benefit.

Even if you don't have to explain about other changes, you can easily find out by referring to the explanation of how you can get the benefit of lowering only the price as the number of purchase requests increases.

The joint purchase server and the purchase application terminal that can be used by one or more purchasers can be connected to each other through a network communication network including the Internet. E-commerce System (or co-purchase server and one or more purchasers) Purchase request group In the joint purchase method using an e-commerce system) in which the sale application terminal available to the terminal and the seller can be connected to each other through a network communication network including the Internet,

The joint purchase method according to the present invention consists of the following steps (or means).

(Step (or means) of transmitting public purchase announcement information, including that the purchase application benefits are matched for each of two or more purchase application quantity sections, to the joint purchase server;)

-In this step (or means), as shown in Fig. 10, the seller provides the site operator with the conditions for joint purchase, including the correspondence of different purchase application benefits for each of two or more different purchase application quantity sections for a specific product. This is a step (or means) input by the operator or directly by the seller.

It is self-evident that different purchase application prices are considered to be corresponding even though different purchase application prices are not corresponded to different purchase order quantity sections in the joint purchase announcement, and a specific discount rate is matched to different normal prices. It belongs to the scope of rights. This is because a discounted price is derived when a discount rate is applied to the usual price.

In principle, a benefit must have two or more conditions that are compared with each other, but in this application, a matter to be fulfilled by a buyer and a matter to be fulfilled by a seller can be referred to as a benefit in this application.

In this step, a narrower range of steps can be created as follows by adding the limited phrase'so that the price does not change even if the purchase request quantity section is changed or there is a section in which the price fluctuation is extremely small .

(So that the price does not fluctuate even if the purchase request quantity section is changed or there is a section with very little price change,

The joint purchase announcement information including that the purchase application benefits are matched by two or more purchase application quantity sections for the product to be traded is sent to the joint purchase server. Sent Is a step (or means) ;)

The transformation step corresponds to each purchase request quantity section as shown in Fig. 10, Fig. 11, Fig. 12, Fig. 18, Fig. 19, or Fig. 20. It is a step (or means) to ensure that there is no change in price or a section in which price fluctuations are extremely small even if the purchase request quantity section changes among the contents of the purchase application benefit conditions. As it changes, only additional products change, so from the buyer's point of view, the price may not be a factor for choosing which purchase request benefit to choose.

Products with a paid price are also useful, but the price is free from the beginning, such as insurance, internet subscription, and mobile phone subscription products, and will be more useful for products that only require a contract, and it can be more profitable in terms of margin for sellers. .

The following steps (or means) are described in all cases, regardless of whether there is a change in the price, so that there is a section where the price does not change even when the number of purchase requests is changed. For the subsequent steps (or means) in which purchase application benefits are matched for each purchase request quantity section, please refer to the steps described below.

Through the joint purchase server, the purchase application terminal provides information on the joint purchase announcement including that the purchase application benefits are matched by two or more purchase application quantity sections for the product to be traded. (Or the sales application terminal: SS ?) To the connected terminal including Accepted Step (or means);

-In this step (or means), as shown in Fig. 10 (~ Fig. 20), the seller determines the conditions for joint purchase including that different purchase application benefits are matched by two or more different purchase application quantity sections. This is a step (or means) of providing the information to the operator so that the joint purchase announcement information entered by the site operator or directly entered by the seller can be displayed on the purchase application terminal.

When a specific discount rate is applied for each of two or more purchase request quantity sections, it is recommended that different discount rates be used for each purchase request quantity section, but joint purchases may be conducted so that the same discount rate is applied if necessary even in different sections.

And, a specific discount rate may be 0%. In other words, there may be a section of the number of purchase requests to which the normal price is applied.

In this step, a more specific step (or means) can be created as follows by adding a limited phrase `` so that the price does not change even if the purchase request quantity section is changed or there is a section in which price fluctuations are extremely small . .

Even if the purchase request quantity section changes, the price Unchanged So that there is a section in which price fluctuations are very slight,

Through the joint purchase server, the purchase application terminal provides information on the joint purchase announcement including that the purchase application benefits are matched by two or more purchase application quantity sections for the product to be traded. (Or the sales application terminal: SS ?) To the connected terminal including receive Step (or means) to be taken;

The transformation step corresponds to each purchase request quantity section as shown in Fig. 10, Fig. 11, Fig. 12, Fig. 18, Fig. 19, or Fig. 20. It is a step (or means) to ensure that there is no change in price or a section in which price fluctuations are extremely small even if the purchase request quantity section changes among the contents of the purchase application benefit conditions. As it changes, only additional products change, so from the buyer's point of view, the price may not be a factor for choosing which purchase request benefit to choose.

Products with a paid price are also useful, but the price is free from the beginning, such as insurance, internet subscription, and mobile phone subscription products, and will be more useful for products that only require a contract, and it can be more profitable in terms of margin for sellers. .

From a seller's point of view, it is often more profitable to provide an additional product (or even higher) to the buyer than to lower the price. This is because the cost of additional products supplied is below the price of more supplied products anyway. If the additional product was originally handled by the seller who requested the joint purchase, the cost will be lower.

Even if the additional products were not handled by the seller who requested the joint purchase, the cost of procuring by the seller would be lowered because it is a large quantity of joint purchase anyway.

The following steps (or means) are described in all cases, regardless of whether there is a change in the price, so that there is a section where the price does not change even when the number of purchase requests is changed. For the subsequent steps (or means) in which purchase application benefits are matched for each purchase request quantity section, please refer to the steps described below.

One of the two or more purchase application benefits is selected and entered from the purchase application terminal used by each purchaser, or purchase application information including the number of purchase requests is input and transmitted to the joint purchase server. (Become and store on the joint purchase server: SS ?) The step (or means) of being;

-In this step (or means), after connecting to the joint purchase server 16 through the purchase application terminal 12 used by each purchaser, the joint purchase disclosure information on the products for sale provided by the joint purchase server 16 is provided. After checking and selecting a specific product to purchase through joint purchase, select the purchase request benefit including the purchase request price desired by the person within the available time of purchase request, and enter the purchase request information for the quantity of purchase request. Purchase request information may be transmitted to and stored in the joint purchase server 16 side.

At this time, each purchaser may directly input the desired purchase application benefits, or a plurality of purchase application benefits provided by the joint purchase server 16 as in the example description through Fig. 10 (~ Fig. 20) above. You can also select and enter any one of them.

There are a variety of optional input methods, including inputting the provided purchase request benefit letters individually, or entering by clicking a button related to the provided purchase request benefits letters.

Selecting and inputting any one has been described in detail with an example of FIG. 4 or 5 above, so the description will end with this level.

In addition, if the number of requests for purchase is one, the number of requests for purchase may be automatically processed as one, even if the number of requests for purchase is not separately input. That is, for a specific purchase request quantity including the case where the purchase request quantity is 1, the purchase request quantity may be automatically input and processed even if the purchase request quantity is not separately input.

In addition, each purchaser may be operated to change the purchase application benefits he or she applied for until the successful bid benefits are determined. As an example of how to change, you can change just by selecting a new purchase request benefit, or cancel a previous purchase request and apply for a new purchase with a new purchase request benefit. If payment was made in advance at the time of purchase request, additional payment or refund may be made according to the changed price settlement rule.

In the case where the purchase application price is paid among the selected purchase application benefit conditions,

Part of the purchase cost reflecting the purchase request price before the successful bid benefits are determined, including when the purchase request information is transmitted from each purchase request terminal through the above joint purchase server Or at the cost of all purchases The step (or method) in which payment is accepted in advance (in consideration of fluctuation benefits)

-In this step (or method), when each buyer applies for purchase, all or part of the purchase price reflected in the purchase request benefit that they apply for and the purchase price according to the number of purchase requests (in consideration of variable benefits) in advance. This is the step (or means) to guarantee your purchase request.

If the purchaser does not pay the purchase cost in advance before the successful bid benefit is determined (mainly at the time of purchase application), the purchase application may be canceled later without any restrictions, causing damage to the seller. In the case of cancellation, payment is received in advance in order to receive a partial refund in the form of a purchase cancellation penalty or to strongly express a purchase intention.

Through the joint purchase server, the purchase application status including the number of purchase requests for each purchase application benefit or the cumulative number of purchase requests for each purchase application benefit applied for purchase for each purchase application benefit is less than the purchase application benefit. A step (or means) aggregated through;

-In this step (or means), the joint purchase server 16 calculates the purchase application status for the purchase application quantity for each purchase application benefit or the cumulative purchase application quantity for each purchase application benefit applied for purchase below each purchase application benefit or to provide.

Here, the cumulative purchase application quantity for each purchase application benefit refers to the total quantity of all the purchase application quantity applied for purchase with a benefit equal to or worse than the corresponding purchase application benefit from the perspective of a buyer.

For example, the joint purchase server 16 may provide a purchase application status including the cumulative purchase application quantity displayed in the "cumulative" column of FIG. 10 (~ FIG. 20).

That is, the "cumulative total" of Fig. 10 (~ Fig. 20) represents the cumulative number of purchase requests for each purchase request benefit applied for purchase below each purchase request benefit.

After the joint purchase application is terminated, through the joint purchase server,

For each purchase application benefit, the cumulative purchase application quantity applied for purchase with a purchase application benefit less than the purchase application benefit, and the purchase application benefit that corresponds to a section larger than the lower limit of the purchase request quantity section condition As the winning bid benefits are determined as benefits,

The purchaser (at least one of the purchasers) who has applied for purchase with the purchase application benefit below the successful bid benefit is determined as the purchased purchaser, and the purchased purchaser can purchase the product while receiving the same benefit of the above winning bid benefit. A step (or means) of deriving a transaction conclusion result including determining that a purchaser (at least one of the purchasers) who has applied for purchase due to the excess purchase application benefit is determined as a purchaser who has not concluded the purchase;

-This stage (or means) is the stage (or means) in which the successful bid benefits are determined according to the end of the joint purchase application deadline, and the result of the transaction is concluded, including the division into the purchased buyer and the non-purchase buyer.

(Thus, unlike the conventional joint purchase method, even though the purchase is a joint purchase, a purchaser who is determined to be a purchaser who has not signed a purchase even though there is a purchaser may occur.)

The description of this step (or means) has been described in detail with the example of Fig. 5 or 10 (~ Fig. 20) above, and thus will not be described in detail.

And, a benefit less than a certain benefit refers to a benefit equal to or worse than a certain benefit from a buyer's point of view. Therefore, a benefit exceeding a certain benefit refers to a benefit that is better than any benefit from the point of view of the buyer.

Of course, part or all of the purchasers who could not be purchased at the discretion of the site operator, the seller's discretion, or a separate remedy are recognized or relieved as purchased purchasers, and thus part of the purchase application quantity requested by the recognized or relieved purchaser. Alternatively, the entire purchase can be signed or partial cost support can be provided.

The step (or method) to be explained later, if the purchase cost (mainly reflecting the desired purchase price) paid in advance by the buyer at the time of purchase application is greater than the purchase cost reflecting the successful bid price, the difference (or method) In the same context as saying that after the refund amount is calculated, it may be possible to refund more than the refund amount calculated at the discretion of the site operator or the seller.

In the case that the price of the purchase application among the selected purchase application benefit conditions or the price among the contents of the successful bid benefit conditions is paid,

After the successful bid benefits are determined,

Through the joint purchase server,

The pre-paid purchase cost (above) received from the purchase application terminal used by the purchaser determined as the purchaser who has not concluded the purchase is refunded (in consideration of the variable benefits),

Among the pre-paid purchase costs received from the purchase application terminal used by the purchaser who is determined as the purchaser who has signed a purchase, Difference The step (or means) in which the cost (or more) is refunded (in consideration of variable benefits);

-In this step (or means), the joint purchase server 16 refunds the purchase cost previously paid by the purchaser determined as a purchaser who was not able to purchase after the joint purchase is terminated (in consideration of fluctuation benefits), and the purchaser concluded in advance the payment of a purchase price in excess of the purchase cost of the winning bid reflects pre-payment fee (more) (in view of the fluctuations benefits) steps which reimbursement is (or means).

In other words, the final selling price is determined by the successful bid price, and the purchase cost reflecting the successful bid price is subtracted from the amount paid in advance by calculating the purchase cost reflecting the purchase request price initially by the buyer. ) Refund.

It's almost unlikely, but it could give you more refunds than the'rest' amount above. That's why they said that they would refund'more than' the cost of the difference. In addition, the word'abnormal' in the refund of other expenses in different parts of the present application is also used with the same intention.

In addition, since the present invention does not apply for a patent on a method of refunding some amount of the amount paid by card, that is, it is not a patent application for electronic payment among the patent fields related to e-commerce, the problem to be solved in the present invention I think it is not,

To mention reimbursing the amount paid in advance by card,

In other words, to mention a few ways to refund the amount (or more) of the amount (or more) by subtracting the purchase cost reflecting the successful bid price from the amount paid in advance to the buyer who paid in advance for the amount exceeding the purchase cost reflecting the successful bid price with a card. It looks like this (other methods are possible).

1. Automated payment of purchase costs that have already been (carded) payments canceled and new successful bid prices reflected.

2. Charge the amount paid in advance on the card invoice in a positive amount, and charge the difference (= amount equal to the amount paid in advance minus the purchase cost reflecting the successful bid price) in a negative amount. As a result, the successful bid price It is summarized by paying the reflected purchase cost (currently, if there is a price change when the airline changes the reservation, it is handled in this way.)

3. The credit card company remits the difference between the customer's bankbook

4. Remittance of the amount that the seller paid in advance to the customer's bankbook minus the purchase cost reflecting the successful bid price (the seller bears the loss of card fee)

5. Accumulate points or cyber money at the credit card company by subtracting the purchase cost reflecting the successful bid price from the amount paid in advance (can be converted into cash at any time).

6. Accumulate points or cyber money on the operating site by subtracting the purchase cost reflecting the successful bid price from the amount paid in advance (can be converted into cash at any time).

In addition, the following steps (or means) may be further added to the joint purchase method according to the present invention.

In the case that the price of the purchase application among the selected purchase application benefit conditions or the price among the contents of the successful bid benefit conditions is paid,

After the successful bid benefits are determined,

Through the joint purchase server,

The pre-paid purchase cost (above) received from the purchase application terminal used by the purchaser determined as the purchaser who has not concluded the purchase is refunded (in consideration of the variable benefits),

Purchases used by the purchaser who signed a purchase (in consideration of fluctuation benefits) for the purchase cost that is insufficient compared to the purchase cost that reflects the successful bid benefit in advance payment received from the purchase application terminal used by the purchaser determined as the purchaser The step (or means) received from the application terminal;

-This step (or method) means that when the amount paid in advance by the buyer before the successful bid price is determined is less than the purchase cost reflected in the successful bid price, the shortfall is paid more. Will be omitted.

If the cancellation of purchase from the purchase application terminal used by any of the purchasers applied for purchase through the above joint purchase server is accepted after it is determined as the purchased purchaser, the purchase request is canceled in advance received from the purchase application terminal used by the purchaser. A step (or means) in which part or all of the paid purchase cost is redeemed as a purchase cancellation penalty (in consideration of the variable benefit) and the balance (or more) is refunded (in consideration of the variable benefit) if the balance remains;

-In this step (or means), if the purchase request can be canceled after it is determined as the purchaser who has signed a purchase among the purchasers, part or all of the purchase cost previously paid by the purchaser as a penalty. This is the step (or means) to compensate the seller's losses and ensure the reliability of the transaction by redeeming it (in consideration of the fluctuation benefit) and providing it to the seller.

In other words, from the point of view of the seller, all buyers who applied for purchase were determined to be sure to purchase if they were determined to be purchasers, and they applied for sale by lowering the selling price as much as possible through the calculation of the profits of the peeled polymorphism, and the buyer applied for purchase later. If canceled, even if the winning product is sold, the profit may be much lower than originally thought, or damage may occur. Therefore, a predetermined penalty is given to the buyer who cancels the purchase request.

Before the successful bid benefits are determined, including the time when the sales information is transmitted (from the sales application terminal) through the joint purchase server, payment for the sales deposit ( Byeon Hae A step (or means) that is accepted in advance, taking into account the choice;

-In this step (or means), in order to compensate for the loss of the purchased buyers that may occur in the case of canceling the sale or not performing the product provision smoothly even though the purchaser has been concluded, a sales deposit from the seller (mainly This is to provide part or all of the pre-paid sales deposit to buyers who have signed a purchase (in consideration of fluctuation benefits) if the seller does not fulfill his obligations after receiving payment in advance). It is to secure.

After the purchaser who signed the purchase is determined,

In the event that cancellation of the sale is accepted from the sale application terminal used by the seller through the above joint purchase server, or information that the seller has not fulfilled the obligations according to the sales right granted to the seller is received, the pre-paid sales deposit is (in consideration of the fluctuation benefits). ) Returned or

Refunding the sales deposit (or more) to the seller (in consideration of the fluctuation benefits) when a normal transaction is made (or means);

-As described above, in this step (or means), if the seller cancels the sale without a justifiable reason or does not perform product provision smoothly, the seller returns the bid deposit previously paid in order to compensate the loss of the buyers who signed the purchase. It is a step (or means).

When a normal transaction is made, the sales deposit will be refunded to the seller.

In the case that the price of the purchase application among the selected purchase application benefit conditions or the price among the contents of the successful bid benefit conditions is paid,

After the successful bid benefit is determined through the joint purchase server,

The payment for the total purchase cost compared to the purchase cost reflecting the above winning bid benefits from the purchase application terminal used by a new purchaser or a purchaser determined as a purchaser who has not signed a purchase is accepted (in consideration of fluctuation benefits) or

The purchase cost, which was previously paid (in consideration of the fluctuation benefits) received from the purchase application terminal used by the purchase application terminal used by the purchaser who was determined as a purchaser who was not able to sign a purchase due to the purchase request benefit exceeding the above-mentioned winning bid benefits, is the purchase cost reflecting the above winning bid benefits Including that payment for insufficient purchase cost is accepted (in consideration of fluctuation benefits) from the purchase application terminal used by the purchaser determined as the purchaser who has not signed the purchase.

It is acceptable to apply for purchase with the above winning bid benefits, including accepting that the total purchase cost is accepted for payment (in consideration of the variable benefits),

A step (or means) in which a buyer who is determined as a new buyer or a buyer who has not signed a purchase is further given an opportunity to purchase a product in addition to the winning bid;

-This step (or means) is a step in which an opportunity to purchase a product at the successful bid price is given to a buyer or a new buyer who has been determined to be a purchaser who has not concluded the purchase because a purchase request is made at a purchase request price less than the successful bid price (or Means).

(If more opportunities are given,

-New buyers can pay the purchase cost reflecting the successful bid price,

-Including the need for an additional step (or means) of additionally paying the insufficiently paid amount by the purchaser determined as the purchaser who has not made a purchase.

That is, the amount paid by the buyer in advance

In the case of less than the successful bid price multiplied by the number of purchase orders ordered at the time of purchase request by the purchaser determined as the purchaser who has not concluded the purchase

The amount paid by the buyer in advance is the amount obtained by multiplying the successful bid price by the number of purchase requests ordered by the purchaser at the time of purchase

Subtracted

This includes the need for an additional step (or means) for the purchaser to pay.

(- Including that the step (or means) of additionally paying the insufficiently paid amount by the buyer determined as the purchased purchaser becomes necessary.)

That is, the amount paid by the buyer in advance
