Price determination for items of low demand

A computer-implemented system that facilitates establishing prices associated with items, comprising:

• a clustering component that clusters a collection of non-identical items into a plurality of disparate sets of non-identical items;
• a pricing component that receives one or more of active bids and stored bids and simulates an auction of at least one non-identical item within a selected set of non-identical items as if the non-identical items within the selected set were identical to determine the price associated with the at least one non-identical item;
• a calculating component that generates an estimate of demand associated with an item within the collection of non-identical items, the item purged from the collection of items if the estimate of demand is above a threshold;
• a scaling component that scales a bid of the one or more of active bids and stored bids and that is associated with an item within the plurality of disparate sets of non-identical items based at least in part upon the estimate of demand associated with the item;
• and
• a display component that displays an advertisement associated with a purchaser that bids above the determined price.
