My alarm bells are ringing all over the place with this one.

As Louise said, it sounds like he used his email as the To:, and Bcc'd, which is a common spam/scam tactic.

The poor grammar is also a flag to me.

Also, asking about money order or check. I don't accept money order or checks because they are now very, very commonly used as a scam.

A scammer will order a prodcut or service from a small company that costs $800. Then they'll send a money order for $1500, saying, "Hey, can you refund me the difference." The poor sap/mark then deposits the $1500, and takes $700 out of their account, sending it as either a legit check or a legit money order, to the customer as a refund. Then the original money order turns out to be a fake. The sap/mark is now out $700 of their own money, has to pay bank fees, and may be investigated by fraud, and is even more screwed if they already sent the product or performed the service!

If you think they might remotely be legit, insist on payment by PayPal or some other secure payment method. As many people as there are that rant about PayPal, anymore, it really is safer than money orders and checks.
