Okay, if you were the seller in this case, what would you do?
I bought a pair of jeans on ebay, the guy sent them over and they looked fine. When I uncuffed them, a bunch of dirt fell out and there was lint and dust in there. It was disgusting. Thing is, I did this after I tried them on and they fit pretty damn well.
What do you consider a fair outcome in this case?
Brush them and wear them.
