I have a couple issues regarding USPS MO's. Again the only time i've been taken in decades was right here on our trader. filed USPS complaints, follow ups and nothing. OP got banned and that's it. The Other is our local PO got robbed just before we left the PRK. Thieves stole all the mail, cash, stamps and, most disturbingly, the MO machine,along with all the boxes of blank MO's and the Computers that ran it. Was told it was a well organized gang who specialized it hitting POs. Not sure what safeguards are out their but you're basically on your own. Maybe a PO type can chime in.
