Online transaction tool

A non-transitory computer-readable medium that stores instructions for facilitating sales transactions between multiple computers in communication over a network, the instructions being executable by one or more processors to perform operations that include:

• (a) identifying a transaction, including an item that is offered for sale on an online medium, the item being associated with (i) a list price that is published to prospective buyers, and (ii) a minimum designated price that is undisclosed to users of the online medium;
• (b) detecting one or more offers for the item from one or more bidders;
• (c) when at least a first offer of the one or more offers is equal to or greater than the minimum designated price but less than the list price, perform one or more operations to designate the transaction as complete based on either the first offer or the highest offer;
• and
• (d) when the first offer is less than the minimum designated price:
• prompting the seller to reduce the minimum designated price;
• and
• providing an interface for the seller to place an alias offer under an alias, including implementing an alias bidding rule in which the alias offer must be below the minimum designated price but can be higher than the first offer, the alias presenting the seller as another bidder on the online medium.
