Main Auctions
A Main Auction is one in which bidding raises the price incrementally. Main auctions can have a Reserve Price, and use Proxy Bidding.

The winner of a Main Auction is the person with the highest bid at the end of the auction. The auction is considered successful if the Reserve Price has been met. If the Reserve Price was not met, the auction is considered unsuccessful and the item owner is under no obligation to sell the item.
