Using 1-click bidding
To help you avoid being outbid, we offer 1-click bidding during the final 60 minutes of a listing. When you use 1-click bidding, we automatically raise your bid by one increment. To use 1-click bidding, you need to be signed in to eBay and have at least one previous bid on the item.

How automatic bidding works

When you place a bid, you enter the maximum amount you're willing to pay for the item. The seller and other bidders don't know your maximum bid.
We'll place bids on your behalf using the automatic bid increment amount, which is based on the current high bid. We'll bid only as much as necessary to make sure that you remain the high bidder, or to meet the reserve price, up to your maximum amount.
If another bidder places the same maximum bid or higher, we'll notify you so you can place another bid. Your maximum bid is kept confidential until it is exceeded by another bidder.

Here's an example:
The current bid for an item is $10.00. Tom is the high bidder, and has placed a maximum bid of $12.00 on the item. His maximum bid is kept confidential from other members.
Laura views the item and places a maximum bid of $15.00. Laura becomes the high bidder.
Tom's bid is raised to his maximum of $12.00. Laura's bid is now $12.50.
We send Tom an email that he has been outbid. If he doesn't raise his maximum bid, Laura wins the item.
