To avoid issues like this, I ALWAYS offer a 100% satisfaction guarantee. I've sold a bunch of stuff on the internet. I've had one item returned, and it was a high dollar rifle. The guy that returned it sent me well over $200 worth of bullets gratuitous for the hassle free transaction. I later sold the rifle to a satisfied buyer for MORE than the first go around.

Crap like this just isn't worth dealing with. Nobody wins.
