Abstract: System(s) and method(s) for offering one or more items, for sale or for purchase, for a specified period of time during which participants bid to purchase or sell the items. The system provides each participant an indication of how their bid compares to bids placed by others. The system does not disclose the bid details of other participants. By providing this bid range of information, each bidder has a sense of their general bid position (not knowing others specific bids), compared to all bidders and by this means, the overall price offered for the item may be driven up or, in the case of offer to buy bid, driven down.
