SOLUTION: A commodity record Ki for a retail store containing the price 20B for each commodity is presented only to a retail store until a corresponding due date 20D. The record Ki that has passed the due date 20D is moved to a commodity table 30 for the public and shown to consumers other than a retail store. On this occasion, the corresponding due date 20B and so forth are updated for the consuming public. In this way, under the due date, a classification of time, the record Ki is presented to different objects that are to be customers. Therefore, the retail store can sell easily the commodities purchased based on the transaction information presented until the due date without a competition to consuming public until the above time limit even though the corresponding price 20B has been updated to the price for the consuming public and sold.
