In the U.S. you can make the items private so they can't see the individual item you sold in your Feedback Profile. But as far as the comments go you can not have a seller account and have private feedback where they can't see the comments.
Thank you.
And does anybody know of a good credit card (prepaid preferably) to use for eBay? I was looking to get Cashplus Mastercard Gold, but I read on some posts that it doesn't work anymore... anybody knows of one? Preferably UK based.
