Next, the product presentation device 1 transmits a product information acquisition request to the product information DB 3 (step S103). The product information DB 3 transmits the product information 321 stored in the storage unit 302 to the product presentation device 1 (step S104). The product presentation device 1 acquires the product information 321 from the product information DB 3 and stores it in the storage unit 102 (step S105).

Next, the control unit 101 (product calculation unit 22) combines products based on the product price of the product information 321 and obtains a combination of products whose total amount matches the input amount (step S106). In step S106, for example, a list 121 of price combination patterns as shown in FIG. 9 is stored in the storage unit 102 of the product presentation device 1, and the control unit 101 stores the corresponding total of the price combination pattern list 121. A predetermined number (for example, three) of combination patterns are randomly selected from the combination patterns of the forehead. Then, a product having a price included in the selected combination pattern is selected from the product information 321. At this time, if a plurality of products having the same price are registered, the control unit 101 randomly selects a product from those products.

Specifically, for example, as shown in FIG. 10, as a combination pattern in which the total amount is "408" yen in the list of price combination patterns 121, a combination of "200 yen, 158 yen, 50 yen", "104 yen". It is assumed that the combination of "154 yen, 150 yen" and the combination of "300 yen, 108 yen" are stored. The control unit 101 (product calculation unit 22) of the product presentation device 1 randomly selects a plurality of combination patterns to be used from the list 121 of the price combination patterns, and sells the products with the product prices included in the selected combination patterns.

For example, when the combination pattern of "104 yen, 154 yen, 150 yen" is selected, the control unit 101 uses the product information 321 to obtain a product having a price of "104 yen", a product having a price of "154 yen", and "150 yen". Select a product of "yen". When a plurality of products of "154 yen" are registered in the product information 321, the control unit 101 randomly extracts one product from the products of "154 yen". In this way, the control unit 101 calculates the combination of products whose total amount is "408 yen".

Further, in step S106, the product presentation device 1 may include "funding" in the product to be presented. In this method, if the combination of products whose total amount matches the input amount cannot be calculated, the amount of change is regarded as "funding". In the case of "funding", bookmarks, information pamphlets, etc. may be presented in place of the products.

Further, as shown in FIG. 11, a list 322 of product combination patterns may be set in advance on the store side and registered in the product information DB 3. As shown in FIG. 11, the list 322 of the product combination patterns stores a plurality of product combinations and their total amount. For example, as a combination having a total amount of "300 yen", a combination of products having pattern numbers "101" to "104" is stored. The pattern number "101" is a combination of "** gum, 〇〇 juice, XX bread", and the pattern number "102" is a combination of "○ △ chocolate, △ coffee, 〇〇 gum". The number "103" is a combination of "△△ tea, × ○ onigiri, 〇〇 gummy, △△ chocolate", and the pattern number "104" is "□ ○ cookie, △ coffee, ** gum, 〇〇 gum". It is a combination of. The product presenting device 1 randomly extracts a predetermined number (for example, three) from the list 322 of the product combination pattern so that the total amount of the input amount and the product price acquired in step S102 match.

Further, in step S106, the control unit 101 (commodity calculation unit 22) does not refer to the price combination pattern list 121 or the product combination pattern list 322 as described above, and is inserted each time a coin is inserted. The combination of products according to the coins may be calculated in real time.
