This is a second scammer within less than 30 days that buys items and leaves a negative feedback in order to get item for free. But best of all he will not change his feedback after you will refund him. There are 6 sellers that have reported the guy within 2 weeks time and the guy is still buying more and more.
How much longer we can take this or how many sellers he will need to scam before he can get suspended. The previous guy got away with 300 negative feedbacks before ebay suspended him.
