I had been on the hunt for a Moto G Stylus but was striking out in my search of Walmart locations. I ran across this Moto One Action Phone that has the same 128gb of storage and screen.
Two locations I visited had it at the $87 price point - it's in a slim purple box in the cage behind the counter (at least at my locations) so you may be able to spot it before asking for it.
The 1st location could not figure out how to ring it up. The 2nd location knew to print off the barcode from the WARP system and then ring it up with that code.
Walmart shows it for $349 on their website. The box they gave me had a clearance sticker that said $261, but it rang up $87. I'm happy - this will be a gift for family. Hope this helps someone else here.
