Abstract: As disclosed in this document, various methods, computer-readable media, and/or computer systems are described for providing search-related services. These search-related services include providing an item list to one or more computer users in which a computer user can add an item for monitoring and/or bargaining with an advertiser. In responding to a search query, a search results page is generated that includes responsive search results. The search results page further includes one or more advertised items. Proximate to at least some of these advertised items is a user-actionable control which, when activated by a computer user, causes the advertised item to be placed on an item list corresponding to the computer user.

Abstract: Systems, methods, and computer-readable storage media are described for providing an item list to a computer user. An item list is provided in which a plurality of computer users each have a corresponding item list into which a computer user can add entries for various item offered by vendors. Upon receiving a user-initiated indication to add an item to the computer user's item list, an entry is added to the item list along with a user amount indicative of an amount the user is willing to pay for the item. After adding an entry to the item list, a minimum price is determined from each of a plurality of vendors offering the item. A vendor (from the plurality of vendors) is selected and an offer is generated for the user on behalf of the vendor.

Abstract: Systems, methods, and computer-readable storage media for providing a vendor-independent item list to a computer user are presented. A vendor-independent item list is provided in which a plurality of computer users each have a corresponding item list upon which a computer user can add entries for various items offered by vendors. Upon receiving a user-initiated indication that the user would potentially like to add one or more items from a currently-viewed web page, a process identifies item information from the web page and presents the item information (including information for at least one item) to the computer user. Upon receiving a selection from the computer user of a presented item, an entry for that selected item is added to the computer user's item list. The computer user and one or more vendors can interact with offers and counter-offers.
