I'm dealing with a real d-bag buyer right now. I was selling some figures, and gave buyers an option of loose or packaged. Buyer paid for them loose, so I opened the packages and shipped them that way. Buyer got these and immediately demands a full refund, because they were opened. I explain that my auction description was clear, and that they paid for loose, but that I will happily refund the purchase price minus shipping to them, or even ship the empty boxes for the cost of shipping (these are resealable). Buyer essentially says, "No, that doesn't mean they're new. Refund me now."
I just responded that I never said they were new in the auction (I left the new/used status blank), and both of my previous offers still stand.
I am fighting this now out of principle because the buyer is a moron who didn't read the auction description, and I surely don't see why I should have to eat my shipping cost to them for that. But I can only see it ending in a negative feedback for me. And for a $20 item, no less. Oh, well. ____ it.
