An enhanced online auction system enables users to submit item-wanted postings in addition to item-available postings and facilitates deferred pairing of buyers and sellers. Users such as buyers, sellers, traders, and agents may use the auction system to search the item-wanted postings, the item-available postings, or both. Item-available postings may be offered for auction, immediate-sale, or best-offer sale. Item-wanted listings may be solicited for reverse-auction, immediate-purchase, or best-offer purchase. In one embodiment, a commerce server of the present invention includes a data store that stores postings corresponding to items offered-for-sale and items wanted-for-purchase, a query module that finds postings within the data store, and a browser interface module that serves web pages for receiving listing criteria and display listings that match the listing criteria. Item-wanted listings may be marked with an identifying mark in order to distinguish item-wanted listings from offered-for-sale listings.
