The hard part is finding any of these that will accept anything but cash for MO. It has happened occasionally, so I don't think WU hard codes to prevent it.

I don't see any functional difference between WU and MG MO's. The difference just lies in where you buy them.

At one Stop-N-Rob store I asked the clerk if he could take debit for a WU MO. He put one hand below the counter, stared at me for a long time, eventually said "maybe", continued staring. I decided just to get a coke, paid with cash. Call me a wimp if you like, but MS is enough fun without getting ventilated for fumbling a card.
