As far as I know you can end a listing whenever you want, regardless of bids. I have had many listings I was watching ended. Most people choose the error in listing reason. The only problem I would think you would enctounter is people avoiding your listings if you do it frequently...I did that to one seller who ended like 5 I was watching in one week. Seemed excessive and exploitive to me. But one listing? Nah, it's a drag relisting things over and over. I do it all the time, relist that is. It sucks. I just relisted a brand new pair of joey stretch like 5 times before someone bought them. Spent probalby $10 of the $99 I made. PITA!

BUT, morally? I don't think it's a moral issue really, more ethical to me. It's not really right or wrong, it just is. You are not trying to rip someone off, you are trying to get a good fair price for your item. I would not avoid your listings if you ended one. Also, I don't think there is a record of your ending items either so only those who are watching the listing would know.

Is it the listing for the Sammy's with the patches? I watched those, would have bid but I wasn't crazy about the patch thing. Dunno, seemed like you could see it through the hole and I was concerned that it would come off after washing and leave "stuff" or problems with the jeans. If it wasn't those then I don't know why no one wants them.
