As a general rule, never believe a response from a person who says they're going to have some outside company handle shipping. As someone said, they send you a made up certified check, you cash it, they get the product and you get in trouble with your bank for cashing a fraudulent check. If they want to pay by check so bad, make them get a check from the post office and not a bank. The post office ones are harder to duplicate and easier to confirm as real.
