Multiple simultaneous auctions can be monitored and participated in using a single bidding device operated by a single remote bidder. A multi-windowed environment allows for the display of active bidding windows and docked bidding windows. The active bidding windows are fully functional bidding windows and include auction status, product information and the like. The docked bidding windows provide a subset of the information but, nonetheless provide real-time auction status information and allows for bidders to enter bids into the auctioning process without having to move the bidding window into an active status. A customer-identifier selector of identifier allows the remote bidder to associate a customer with a particular bidding window. The customer-identifier advantageously helps the remote bidder to track who purchased items are associated with, as well as providing control structure over the bidding process.
