Last month I sold some old watch cases on the bay to a buyer for $278.00. Payment was received via Paypal. Item was shipped on June 10, 2010 via USPS with Delivery Confirmation. USPS confirmed that the shipment was delivered on June 12, 2010. 2 weeks later the buyer contacted me to that he has yet to receive the item. He had filed a dispute with Paypal. Paypal had just informed me that a delivery signature is require for anything above $250.00 which I just found out. Basically I am screwed out of $278.00! ???
