Question 1

How does proxy bidding work?

Accepted Answer

Proxy bidding lets you set the maximum amount you are willing to pay. The system then automatically bids on your behalf in the smallest allowed increments, only going as high as needed to keep you in the lead — up to your maximum. You only pay one increment above the second-highest bidder, so you will never pay more than necessary.

Question 2

What are the bid increment tiers?

Accepted Answer

Bid increments are based on the current price: $0–$99.99 uses $5 increments, $100–$499.99 uses $10 increments, $500–$999.99 uses $25 increments, $1,000–$4,999.99 uses $50 increments, and $5,000 and above uses $100 increments.

Question 3

What is a soft-close extension?

Accepted Answer

If a bid is placed in the final minutes of an auction, the end time is automatically extended by a few minutes. This prevents last-second sniping and gives all bidders a fair chance to respond. Soft-close can trigger multiple times if bidding continues near the end.

Question 4

Can I retract or lower my bid?

Accepted Answer

No. All bids are binding. You can increase your maximum bid at any time, but you cannot reduce or retract a bid once it has been placed.

Question 5

What happens if I'm outbid?

Accepted Answer

You will receive an email, SMS, and in-app notification immediately when someone outbids you, so you can decide whether to place a higher bid.

Question 6

Is there a maximum bid limit?

Accepted Answer

Bids can be placed up to $1 billion. All bids are in US dollars with up to two decimal places.
