On the other hand, I recently ordered two used Scott catalogues from an
ebay seller, and in the box that arrived there was only one catalogue. The box was taped up on top with clear plastic tape, but the bottom was the old
Amazon paper shipping tape and was NOT retaped in plastic by the shipper. My guess is that the two catalogues were so heavy in the same box, that the seller's failing to reinforce the tape on the bottom of the
Amazon box let one heavy catalogue push the paper tape aside and fall through the opening. But I have no idea what happened or why both didn't fall through. The seller assured me she had shipped both catalogues. I believe her, but I only received one. So how do I prove it? I can't. But I contacted her with the problem. After over a week of back and forth with photos and "what could have happened" discussion, she agreed to refund me for one of them.
Sometimes things actually don't arrive the way they're supposed to.
I've also received the wrong stamps once or twice. And from Europe I recently received an order missing a few stamps that I'd ordered. I checked repeatedly in each case because I assumed I just wasn't seeing the stamps that I'd ordered, but they really weren't in the envelope. Both sellers corrected the mistaken orders after I described the problem to them.
I'm sure there are scammers and cheats out there, but don't take it out on honest people who don't receive what they ordered. I would no longer do business with a seller if they did that, even though I understand their concern.
