Abstract

See full text

A user who repeatedly purchases the same electronic content is entitled to receive a discount price for the additional purchases. This is accomplished by establishing an 'Accounting History' of accounting information that is prepared when the electronic content is repurchased. The price of the repurchased electronic content is set to 'Discount Price,' which is less than the original price at which the electronic content was purchased for the first time. Since accounts are settled based on the accounting information with 'Accounting History' set to 'Discount Price,' the user who is purchasing the same content again can buy it at a discount price.
