It's how business is done on the Internet, reducing the barriers of time and distance and maximizing speed and efficiency. Sell excess inventory fast or purchase parts at a price YOU determine. Find specific equipment or parts or sell them economically. Buyers send out a request for bids, and sellers compete auction-style to provide the best price and service.
Buyers can examine items and prices and then complete their purchase right over the Internet.
No follow-up phone calls, no faxes, no hassles.
