The present invention provides a method and system for enabling an e-commerce website to persist electronic items, such as electronic coupons, gift certificates etc., across multiple browsing sessions. Users are offered electronic items over a communications network during a browsing session. In case the user wishes to save the items for a later browsing session, he/she is prompted for an email address. Details pertaining to the selected items are mapped against the email address. Thereafter, e-mail is sent to the user, containing a URL with the email address of the user embedded in it. Alternatively, entire details corresponding to the items selected during a session are embedded in the URL and in this case they need not be mapped against the email address.

Method and system for enabling unregistered users to manage electronic items across sessions

The current invention provides a method, system and computer program product for designing a catalog with optimized placement of items. Past user transactions are used to estimate the effect of nature and placement of an item on the response of users to the catalogs in terms of items clicked on or items purchased. These estimations are used to optimize the placement of items in a catalog in order to maximize the gains for a merchant specified objective, which can be in terms of revenues, sales or the number of clicks. Various stochastic and deterministic optimization functions are used for the purpose of optimization.
