Thanks to all here who responded & confirmed my feelings, as well as the fishy way the guy wanted to pay.
He wanted to pay with a card, over the phone, and have me ship immediately. All at the PO. He wanted my stuff, but his methods of trying to pay weren't normal. I tried & tried to get him to just buy the m/o and mail it to me, but he didn't want to wait for his payment method to clear.
That Forum admins have been made aware of things, and it's up to them what happens next. I'm not out anything but time trying to help a guy get something he wanted.
I tried,,, but he failed.
Time to move on.
