I wouldn't deposit the M.O. to a bank account. USPS (post office) can scan the money order and tell immediately if it's the real thing or not. If they don't have enough cash on hand, I had them give me what cash they could, and sell me new money orders that I can cash later. That's how things worked on ebay before they made you accept Paypal or some other money transfer service. But then, you are old enough to have had to do that same thing before, I'm sure.
