PURPOSE: A system for differentiating prices of a product according to a member level at an internet web site is provided to allow a seller to obtain regular customers to make continuous profits and sales, and offer a lot of services to the customers, and to allow a buyer to decide a regular web site and thereby buy a product with lower price. CONSTITUTION: When a user accesses a home page, it is displayed(N1). The user selects one of products to be bought on the home page(N2). The user performs a login process and fills in an order document(N4). If the user buys the product as a member, a process(N6) is executed, and otherwise a process(N5) is performed. A server recognizes the member level, classified by the member level variable of the user, and thereby calculates the member level of the user(N7). The server determines the price of the product bought by the user according to the calculated member level(N8,N9).
