Method and system for providing a transaction platform for pre-owned merchandise

摘要

One embodiment of the present invention provides a system for facilitating trading of pre-owned merchandise. During operation, the system receives, at a server, recycle information associated with an item that a first user intends to purchase and stores the recycle information and identification information of the first user in a database. The recycle information specifies identification and price information associated with the item. The system receives, from a second user, a request for an offer price for a for-sale item. The system then queries the database to identify one or more users who intend to purchase the for-sale item, calculates offer prices provided by the identified users for the for-sale item, and provides a list of the identified users and the calculated offer prices to the second user.
