How about you cash the check and don't wire the guy anything, nor ship the boat? You get $6500 to play with for a couple of months (up to three years according to the article Rick posted,) and he's out a piece of paper.

Money making opportunity! Offer bogus things for sale on the internet, but only "sell" to scammers. Cash their checks, keep and invest their money and give the money back when the bank wants it. You get to keep any money you made in the investment!

At the very least, it's a 0% interest loan, with an indefinite payback date.

Hmmm... What should I "sell"?
