SOLUTION: When a commodity is an electronic coupon commodity (YES in ST12), it is selectively processed. When a discounting processing is previously selected (YES in ST13), the discounting processing subtracting an amount equivalent to a point is executed from a unit price (ST14). Then, the commodity is registered (ST16). When the discounting processing is selected (YES in ST13) in accounting processing (ST18) after a closing operation (YES in ST17), a discount amount by an electronic coupon ins printed on a receipt and the validity (discount) of the electronic coupon is informed.
