OVVGC at Walmart
DP, I was able to liquidate 2x$500 OVVGC to BB at WM this morning. Not sure if YMMV or if it will work for MO or not. It didn't ask for a PIN either which is similar to some DPs for MCGC going through without the change payment trick or entering a pin.
Imgur link in r/churning, I'm unable to post URLs here still.
