This question is mainly for those folks who have sold stuff on Ebay but any suggestions would be welcomed. I have some stuff up for sale and the current high bidder on two items has a feedback rating of (-1). He has four feedbacks, three negative and one positive. The last feedback recorded was June of 2001. My question is should I allow this guy to continue to bid? This is a first for me in almost two years of selling on Ebay.
