I would suggest you not pass these types of deals on in this forum especially under your own account name. Mainly because it looked like you, a long term solid member, was selling the item. There was no way to know this wasn't you.
Now for the rest of the story...
It's a scam. The gentlemen in question was "in Europe on his honeymoon" and wanted me to send the money to an iSold it account. I asked him if I could just pay cash and pick it up. He said he did not know where location of the item was at but that he needed to move this quickly. If I provided my name and address he would have someone from iSold it contact me on where to send the money.
Now if I had sent the money and been burnt, I would have come back here slamming your name i.e. tell everyone you're a bum and not to deal with you. Something I am sure you do not want happening.
Better to post only when you have something to sell. I understand your sentiment and wanting to help others but this could have bit you hard.
