<p>The purpose of the present invention is to reduce the possibility of users, who have requested in-stock notifications, from accessing pages for out-of-stock products. An in-stock notification request receiving means (84) of an out-of-stock notification system (1) receives in-stock notification requests for products from users. An in-stock notification means (86) sends in-stock notification to users when products become available. An out-of-stock notification means (90) sends out-of-stock notifications to users from whom in-stock notification requests have been received, when products become unavailable after in-stock notifications have been sent.</p> |
