USPS priorty mail comes with 50$ insurance. As far in your case..i guessing you eat that one, because item is not as described, right?
I have heard or read, folks write that's its your responsibility all the way to their doorstep. This is where signature confirmation comes in. some use registered mail where whenever it changes hands, it gets signed for.
Sorry for being the Debbie-downer. Just my 2cents..thats the reason I use priorty flat rate boxes, tho bubble mailers is the cheaper and cost productive route.
He could also keep the card and give the price difference/partial refund as well.
