eBay is making bidding faster. With 1-click bidding, you enter your maximum bid amount, click the 1-Click Bid button, and your bid will be submitted immediately. There are no extra steps for reviewing and confirming your bid.
1-click bidding appears on auctions where you've already placed a bid. So when you're ready to bid again, click the "Try 1-Click Bid" link. A window opens with the next bid increment already populated. Click 1-Click Bid to enter that bid amount, or type in your maximum bid amount, and then click 1-Click Bid.
The 1-click bid window stays open until the listing ends or you close it.
Remember that when you click the button, you're committing to buy the item from the seller if you're the winning bidder. Make sure that you have reviewed the item description carefully including the seller's description, instructions and accepted payment methods before you bid.
