I just went through the NPB thread and added all those ebayers to my blocked list. I came across a problem a fellow tpfer had, and just came across it again on an eBay listing, so it made me curious. Seller sold the item, buyer paid with paypal, payment cleared, seller shipped, to find out there was a hold on the payment? Money then goes back to buyer and the item is already on its way! Has anyone else have this happen? And how can you prevent this from happening?
