Just for your information.
I was up at my bank today & the bank teller told me that there are a whole slew of counterfeit US Postal Money Orders being "floating around" out there right now.
If you are doing any "on line" business transactions then cash your money orders BEFORE you ship out any "paid for" item.
If I understood the teller correctly...should you accept a worthless, bogus, money order as payment ~ you are basically S.O.L. stuck with it.
