  • Publication number: 20220138673
    Abstract: Problem: This disclosure provides a server and/or the like that can provide an opportunity for a user to confirm purchase of a reserved product. Solution: In a server 200 for a product sales system, a notification device 242 sends a first message including an object for canceling reservation of a reserved product to a user via a message service, enabled to discriminate whether a message has been read, when the product arrives. A cancellation device 243 cancels the reservation when the object is operated in a predetermined time after the first message is marked as read. A determination device 244 determines whether the product is in stock when the object remains unoperated for the predetermined time after the first message is marked as read. A finalization device 245 finalizes purchase of the product when it is determined that the product is in stock.
