PROBLEM TO BE SOLVED: To decide the prices of selling commodities without troubling the commodity purchaser in particular by making the purchaser decide the prices of commodities to be purchased by him based on the result of comparison obtained between the information on the commodity purchaser acquired via a computer system and the information on the commodities which are previously selected based on the prescribed reference. SOLUTION: A commodity purchaser loads a CD-ROM 160 and takes the necessary procedure for purchasing the contents stored in the CD-ROM 160 via a purchaser terminal 300, i.e., a computer system of the purchaser. Thus, the information on the hardware and software constructing the terminal 300 of the purchaser are automatically supplied to a price operation terminal 120. Then the selling prices of the contents are decided based on the supplied information (user information) on the hardware and software. As a result, the selling commodity prices are decided based on the products (hardware and software) forming a computer system of a commodity purchaser and without troubling the purchaser in particular. |
