Proxy (maximum) bidding explained

Proxy bidding lets you enter the highest amount you're willing to pay. The system then bids the minimum needed on your behalf, one increment at a time, up to your maximum — but never above it.

Only the two highest maxima set the visible price: if nobody outbids your ceiling, you win at a price that's often below your maximum. Your maximum stays confidential and is never revealed to other bidders or the seller.

• Set your maximum once — no need to watch the screen constantly.
• The system only steps up one increment above the second-highest bidder.
• You can raise your maximum any time while the auction is open.

If two maxima tie, the earliest bid wins. Combined with anti-sniping, proxy bidding stops you overpaying while keeping a fair chance right to the last second.
