Paying for items using Immediate Payments requires you to pay for the item in order to win it (unlike other cases in which you win on eBay first, then pay for the item). You pay through PayPal with a credit card or with other PayPal funds (including a PayPal balance or a bank account).
To use Immediate Payments, you need to:
Pay first to win the item
Be aware that other members could win the item first if that other member pays first.
Note: Be sure to finish your payment quickly so someone else does not win the item.
To purchase an item using Immediate Payment:
Look for items with an “immediate payment required” link on the item page.
Click the Buy It Now button. If the listing is for multiple items, be sure to specify the quantity you want.
Review your postage address and the total cost of the item on the Confirm Your Payment page.
Click the Continue button to finish up the purchase. Learn how to pay using PayPal.
After payment is confirmed, the item is yours.
Note: If you have previously purchased items from this seller, you'll see a View purchase history link on the listing page. You can click this link to see versions of the item you've purchased.
For items paid for using Immediate Payment that have both a starting bid price and a Buy It Now price, the Buy It Now price disappears when a bid is placed.
