I'm not going to argue the point with you. Somewhere, someone is sitting around inventing ways to screw people using USPS money orders. Just cause you haven't been screwed yet, doesn't mean it can't or won't happen!!!
the post office has been doing this for a really REALLY long time and has it down pat they even have there own investigation and enforcement branch to deal with fraud believe me there is nothing you or anyone else can come up with that they haven't thought of and dealt with already the only way you can get screwed is if you try and deposit a counterfeit M O in the bank but that would just be careless
