The present invention is to provide an electronic shopping mall in which customers can enjoy shopping including discount negotiations. The electronic shopping mall has a shopping mall server (sales management/acceptance processing server 101 and discount server 102) that manages the electronic shopping mall and a shop server (shop servers 103A to 103n) that manages a virtual shop in the electronic shopping mall. In response to a discount request provided by the customer, the shopping mall server responds as to the discount to be born by the electronic shopping mall to the customer. When a request for a further-discount which is beyond the discount to be born by the electronic shopping mall is provided by the customer, in response to such request, the shopping mall server negotiates with the shop server for a discount to be born by the virtual shop managed by the shop server. <IMAGE>
