Many thanks for posting this. One of my local stores had one in stock for a while at $46.96. I've checked Brickseek almost every day and finally today it dropped all the way down to $11 so I picked it up. Wasn't even marked in the case.
Also went to another Walmart and picked up My Arcade Burgertime mini arcade for $5.00 and the My Arcade Dig Dug for $5.00. Also, finally found a copy of Tiny Troopers Joint Ops XL (Switch) for $19.93. It appears a few of my local stores have restocked Tiny Troopers, some at 6+ in stock. For about a month the game was completely missing from my whole area.
Here's the link in case you are still looking for one:
I also saw World of Simulators (PS4, likely Wal Mart exclusive) at every local Walmart except the one closest to where I live. Oddly enough all of them (at multiple stores) were box cutter slashed at the top . I also picked up a copy of that in case it does become hard to find and I regret not getting it.
All in all a good day Walmart game hunting (luckily I was off work today).
