Abstract: Multi-quantity fixed price referral systems and methods are described. A “multi-quantity fixed price” listing is a listing published by an online publication system where a seller is selling a number of identical items for a fixed price for each of the items. The methods may include selecting a category from a catalogue hierarchy used by an online publication system. The selected category may be one of a plurality of categories assigned to listings each describing an item for sale. The listings within the selected category are filtered to select a set of filtered listings. A decay formula may be applied to each filtered listing of the set of filtered listings. One or more of the filtered listings are selected based on a ranking of the filtered listings. A graphical user interface to display the selected filtered listings to the user is provided.
