eBay auction sniping: how last-second bidding works

How eBay's proxy bidding works, why bidding early only raises the price, how to place a last-second bid by hand, and how to decide your maximum from recent sales.

Sniping is placing your one bid in the final seconds of an eBay auction. It is allowed, it is how experienced buyers bid, and it works because of how eBay's bidding is built. This guide explains the mechanics, the arithmetic and the habit that keeps you from overpaying.

How eBay bidding actually works

eBay uses proxy bidding. When you enter a maximum, eBay bids on your behalf only as much as needed to stay ahead of the next-highest bidder, up to your maximum. The current price you see is the second-highest maximum plus one increment, not the high bidder's true limit. An auction ends at the scheduled time, with no extension when a bid lands late.

Why early bids raise the price

Every bid placed early does two things. It tells other bidders the card is wanted, which draws attention and bids. And it gives anyone who wants the card days to decide to go higher. A bid placed with five seconds left does neither. The other bidders' maximums are already in; your bid either clears them or it does not, and nobody has time to react.

Decide the maximum before you bid

1. Look at the card's recent sold prices for the same grade. Our card price pages show the median of the newest sales per grade and how many sales back it up.
2. Decide what the card is worth to you against that number. A maximum at 85% of the recent median leaves room for a deal; a maximum at the median means you are paying market and should expect to win about half the time.
3. Add shipping and tax to what you are comparing, since the sold prices you looked at include the card only.
4. Write the number down. Do not raise it in the last minute because the price moved.

Place the bid by hand

• Open the auction in one tab and a clock in another, or use the countdown on the listing.
• Type your maximum into the bid box ahead of time and leave the cursor on the confirm button.
• Confirm with 3 to 5 seconds left. eBay's servers need a second or two to register a bid; under 2 seconds is a coin flip on a slow connection.
• If you lose, you lost to someone whose maximum was higher than yours. That is the correct outcome; the maximum was the point.

Bid increments

eBay raises bids in fixed steps that grow with the price: 50 cents under $5, up to $10 at $500 and above, and $25 above $1,000. Bidding an odd amount such as $412 instead of $400 wins ties against people who bid round numbers, which is common.

Picking the auctions worth sniping

The best candidates close at quiet hours, carry weak titles, or sit well below the recent sold prices with little time left. The deal finder lists live graded card auctions next to their comps and sorts by closing time, so the evening's candidates are on one screen. On weekends there are more auctions ending than on any other night, and more competition; weeknight and late-night endings are where quiet wins happen.
