When performing checkout processing for a purchased product at a POS terminal installed in a retail store or the like, service points earned for the total amount of payment for the purchased product and an additional amount of purchase required to earn one more service point are displayed on the customer-side screen of the terminal together with a message enticing the customer to earn one more service point. The customer-side screen includes a section in which purchase guide information about products having prices equal to or higher than the additional amount can be displayed, and "Image 1", "Image 2", etc. of such products are displayed in the purchase guide information section. As the additional amount of purchase required and the purchase guide information are automatically displayed, the sales of merchandise can be promoted effectively.
