Do you know what an online auction is? I bet you do, and you probably already considered selling products on the Ebay network, the number one name in the field who built an empire on this method of sales and got millions of people used to buying online for their best offers, taking part in a sort of race to the purchase. Users who are interested in auctions are moved by the chance to get items at low prices and motivated to make a bid which in most cases turns into an immediate raise as soon as they are outbid.
