Proxy bidding allows you to set a maximum bid amount, and the system will automatically bid on your behalf until your maximum bid is exceeded. This allows you to step away from the auction without having to check back every time you are outbid. Proxy bidding is automatically enabled. All you have to do is enter your maximum bid and let the system do the rest for you.
Keep in mind that by placing a bid on an item, you are entering into a binding legal contract to pay for said item if you are the auction winner. DO NOT SET A PROXY BID THAT IS HIGHER THAN WHAT YOU ARE ABLE TO PAY. (see the auction terms and conditions for more information)
