I've been selling on Ebay for over 7 years. Up until the last month, I think I had one or two Paypal Unauthorized Transactions the whole time. Just in the last month, I've had FOUR. All have the required tracking and I will most likely win them all, but what is going on? Not like they are scammy items either. 3 of them are for used clothes that were under $15 each and other was for a $50 pair of Rockport Walker shoes. Anyone else experiencing a sudden increase, or is this just the norm, and I've been extremely lucky up to this point?
