eBay are a little strict about letting you withdraw your bid. They call it a bid retraction, and have a stringent set of conditions that you must meet before you are allowed to do it. Here are eBays three acceptable reasons for withdrawing a bid.
You made a typographical error: This means that you accidentally typed the wrong amount into the bid box, bidding a far higher price than you meant to. This can be scary: imagine bidding $100 and accidentally adding an extra 0! You are entirely allowed to withdraw your bid in this situation, and bid again if you want to.
The items description changed: If you bid on something and then the seller updates the description, you have the right to withdraw your bid. It wouldnt be fair, after all, to force you to take something that you now realise you dont want.
The seller is uncontactable: If emails to the seller bounce and they dont answer their phone, then the auction obviously cant continue, and you can cancel it.
