Some embodiments may provide a method and a system for receiving a first limit price, associated with a bidder, on a first auction-format listing, receiving a second limit price, associated with the bidder, on a second auction-format listing, making a first determination as to whether a first condition exists that prevents a first winning bid from being placed on behalf of the bidder on the first auction-format listing, the first winning bid being at least as favorable to the bidder as the first limit price, and based on the first determination being in the affirmative, selectively making a second determination as to whether a second condition exists that prevents a second winning bid from being placed on behalf of the bidder on the second auction-format listing, the second winning bid being at least as favorable to the bidder as the second limit price.
