Money order question, plz help!!!?

lol thats a good one, i dont belive so, did you keep the receipt stub, you can call the 800 number and find out if the money order has been cashed and who cashed it. Otherwise i dont believe its possible unless the money order was no good to began with, ive gotten some through the mail. If you purchased it at a store, bank or post office it should be good, call the number on the stub from the money order, if you sent the person the stub attached to the m.o well u will never know
