Yes, proxy bidding is enabled.
You can place a Proxy if you like. The Proxy feature allows you to place your maximum acceptable bid for this item. This way, your bids will be automatically increased to the next acceptable bid increment (see 'bid increments' in FAQs) should someone outbid your initial bid.
The Proxy always wins in the event that someone ties your maximum acceptable bid!
All auctions have a reserve or minimum bid. If not met the item will not be sold.
