so here's my question; guy buys a $20 PSA card on ebay for $15 BO this morning. I email him and say hey I offer free shipping for $50; is there anything else you want? His reply

No thanks. In truth, I thought this was for the set because it says from Hockey SET... {in title} I wouldn't have purchased this if I had known. Picture and description obviously show 1 card

Every collector would know, this particular set would not be $15, that's beside the point. I would cancel his transaction and refund his money, I want satisfied customers; However, ebay punishes me if I cancel his transaction, basically it counts against me and I can lose my TRS status.

what would you do? How would you handle this? I have not responded to him yet.
