An objective of the present invention is to accept a "bulk purchase" as a preorder when a customer purchase products, etc., and register preorder information including product codes, purchase conditions, etc., to a sales management server, even if the purchases are not made at the same time. With a sales management server being configured to manage a remaining preorder quantity wherein preorders are placed, verify preorder information at each purchase, and apply a sales price which is predetermined as a purchase condition with a discount from a "bulk purchase" taken into account, it is possible to set an appropriate discount amount which takes a break-even line into account, even with a case in which the same product or service is purchased on a repeat basis with purchase instances being spread out. A configuration is also possible such that the preorder information is stored in a customer-owned membership card. |
