Abstract: Method and apparatus for facilitating a sales transaction between one or more sellers and potential buyers in relation to large numbers of similar units. A seller offers the units to buyers, starting at an initial price. The potential buyers make offers to buy a given number of units at that price. The price is incrementally reduced, with buyers being given the opportunity to bid with each reduction. In other embodiments, the buyer makes an offer to multiple sellers at a given price, specifying the number of units the buyer wants. Sellers offer to fulfil some or the entire offer, and the buyer subsequently reduces the price and makes additional offers until the buyer's requirements are met.
