To attain the objects of the system, a points issuing unit issues points corresponding to the purchase amount of a customer. A points storage device stores the number of points accumulated by the customer. A points redeeming unit reduces a purchase amount of the customer as points to be redeemed. A points issue ratio and a points redeeming ratio can be set for each shop forming part of the online shopping mall.
