I've reached out to Walmart trying to find out what the story was.
As in to CS, or higher than that?
You can get very unlucky or very lucky with walmart. I got $100 WM GC for a wrong listing for an item (and a full refund), and the $15 GC for the GC glitch awhile back (didnt seperate my email address for orders). The only order I got messed over on was for $3 and paid for with the $100 GC, so im up $112.
