Proxy Bid is to win the auction item at the lowest possible price by placing bids on it at the lowest possible increments up to a maximum amount you set.
Basically you enter the highest amount you are willing to pay and the system will bid on behalf of you as prompted by other bids. If any bidder outbid you, our system will intimate you by email.
You can use the proxy bid feature if you are unavailable to bid at the time of auction closing, For example you can set your max bid to $100, and if the other bidders only go up to $40, you would win the item for $41. If someone bids higher than $100, then you would lose the auction.
