I would take some time and research this a little deeper. After looking at the sites listed in his e-mail to you.
1st..I would check this page out from e-gold >>Click Here<<
2nd...The guy has his own money order business saying that it is registered with the BBB of Tampa >>Click Here<< to check it out. I would contact the Tampa BBB and get info.
Just sounds like a long trail to get someone seperated from their money.
I would think that if the guy really wanted his money he would take any money order or at the least a cashiers check.
Good luck
