Dont do it Report it to RJ and the police
I HAVE HAD THAT HAPPEN TO ME TWICE, I had a boat for sale on a local web site and I got several of those exact emails, I played with them and they went as far as sending me a bad check, I took it to the bank and asked them to verify and they siad it was a fraud, I took the check to the police station and they started an investigation. They said they traced it to somewhere in India and they could not proceed. Another guy here at work he had the same thing, I warned him about it but he was money hungry and lost his ass, it was around 10,000 he lost in this scam.
