Abstract: A computer-implemented two-tiered electronic market system includes a data repository storing information corresponding to an inventory of one or more available items and a first-tier electronic market (e.g., a retail tier) that provides a first participant (e.g., a retail consumer) access to the inventory of one or more items in the data repository. The inventory is offered to the first participant under a first (e.g., retail) pricing scheme. The two-tiered electronic market system also includes a second-tier electronic market (e.g., a wholesale tier) that provides a second participant (e.g., a wholesale dealer), different from the first participant, access to the inventory of one or more items in the data repository. The inventory is offered to the second participant under a second (e.g., wholesale) pricing scheme different from the first pricing scheme.
