PROBLEM TO BE SOLVED: To provide a network shopping system which contributes to prevention against an omission of article purchase and a mispurchase. SOLUTION: In a relative article DB 257, main bodies and options or articles which tend to be used at the same time, i.e., mutually relative articles are stored while being made to correspond to each other. When a user puts an article to be purchased in a shopping cart, the relative article DB 257 is accessed to retrieve and recommend relative articles to the user. |
