PROBLEM TO BE SOLVED: To powerfully motivate many customers to buy specific used books at an early stage in a system for promoting object purchase. SOLUTION: An object purchase site accessible from an external computer is provided. The purport of being 'during a specific object purchase campaign' and the 'present purchase price' of the object are displayed in the image of the site. When an offer to sell the object is received from a customer, the 'present purchase price' shown in the image is reduced. |
