Last year I had the exact opposite situation. I won a set of N-frame diamond magnas while bidding on a described set of K-frame, (with poor pictures).

I was in contact with the seller, who was very concerned with their ebay rep, and offered a credit back to my paypal account. More than fair and no waiting in line at the post office for a return. I'll find a use for them sooner or later.
