I recently made a high-end bag purchase. Due to my previous painful experiences (fake bag with no return address), I would like to have seller's complete mailing (not P.O. Box) before processing my PayPal payment. But the seller wouldn't give that to me but just pushed me for the payment. This seller doesn't have a lot of feedbacks, but all her feedbacks are good from selling high-end bags. I don't understand what this seller's concern. Should I give in and make the payment? If she has nothing to hide, why she wouldn't give me her complete contact info?
