Im not a moron, I would NEVER ship anything until I brought the MO to the Post Office, and verified it was legit, and got the cash.
The point I'm making is that you really can't tell it's legit until it's too late. Even if the Post Office tells you it's ok, and gives you cash. If it turns out to be a forgery, the PO will come back to you and demand their money back. It happens all the time. I'm just trying to spare you the shock, not call you a moron. Even otherwise intelligent people have been duped into thinking they're protected by using PO money orders, when they are not.
