[0011] That is, the commodity sales system of the present invention comprises:
An object of the present invention is to provide a product sales business model and a product sales business method for transferring sales information of goods via a network such as the Internet and storing and displaying the information on a terminal of a purchaser.

[0012] Specifically, the commodity sales system of the present invention comprises:
A seller terminal that transfers information on the product purchased by the purchaser and information on advertisements and the like to the purchaser terminal of the purchaser via the network, and accumulates information on the purchased product received from the seller terminal and makes money. And a purchaser terminal having a function of displaying the payment information of the seller and the advertisement information transferred by the seller. The purchaser terminal also has a function of comparing the accumulated purchase information and advertisement information, and extracting and displaying bargain product information.

[0013] As a result, the information of the purchased merchandise is transferred from the seller terminal to the purchaser terminal and stored in the purchaser terminal, so that it is not necessary to leave a receipt or the like at a later date to collect the information in a household account book. . Further, since the information of the purchased product is transferred from the seller terminal to the purchaser terminal, the seller does not need to issue a receipt or a statement on paper.

[0014] Further, since the information of the purchased merchandise is transferred from the seller terminal to the purchaser terminal, there is no need for the transfer by the purchaser, and no mistake is made when the purchaser posts from the receipt to the household account book. . Furthermore, since the information on the purchased merchandise is stored and managed in the purchaser terminal, it is possible for the purchaser to save troublesome processing of the household account book.

On the other hand, since the advertisement information is transferred to the terminal of the purchaser of the product that has used the store of the seller at least once, the advertisement is issued to the person who is likely to purchase the product from the seller. Becomes possible. Further, since the purchaser terminal manages the product purchase history and the product purchase information, it is possible to compare the product to be purchased next time with the purchase history up to now.

[0016] Therefore, the purchaser can easily manage the cash accounting and the purchaser can easily provide the seller with information necessary for examining the commodities to be purchased next time.
