I never had problems as well, sales ranging from 6k to .99 cents, not one return on ebay. But this is setting a precedence. The culprit is paypal, the buyer is abusing the policy set by them. I had a very positive interaction with the paypal rep, and it was the second person I spoke to. The first one didn't give a rats , just went through protocol. The second rep listened and understood the situation and even asked me to upload the grader notes from cgc website. Felt confident after the phone call, but who knows, the status is still in the review stage. The fact that the buyer shipped the book back without a decision being made is puzzling. Either he is very confident or he has done this before. If the decision is in his favor, I am done using paypal. Just morally wrong, who wants to deal with a return six months after the fact.
