How to remove an item on Ebay that has few bids, which sold it to someone?

You should not have it on the list if it will sell somewhere other than eBay.

Let the auction closes and once closed, send the winning bidder a note or e-mail of apology before you pay. I'd be crazy if I was the person receiving the note, so tired of what their plans are for an item that does not sell the next time you do something like this.
