Fellow Scholars: I recently had a difficult time with USPS regarding a purchase here on QRZ. The seller shipped his product USPS 2-day priority, with a Priority shipping label. Unfortunately, the actual shipping box was a Priority EXPRESS box, and the shipper used some white labels to obscure the EXPRESS part. The shipping post office accepted the package and charged the seller the Priority 2-day rate. When I received the package I was dismayed to find out there was postage due- quite a bit of postage due. My only recourse per the post office was to refuse the item and have it returned to the seller (who already had my money). I paid the extortion money and informed the seller of what had happened. To his credit, he offered to split the extra shipping expense. I'm certain this was an innocent error on the part of the seller, but I would be careful in dealing with the post office- this feels like a "gotcha" to me. In the future, I will probably insist on FedEx or UPS for shipment, even if I have to pay a bit more.
