I have never purchased ammo at Walmart. The last time I saw their prices, they were more expensive. Not worth having them track down the "guy with the key" either; at least that's the way they did it at the local one.
maybe now mass gun shops will start stocking ammo in larger quantities?
Oh wait they are dependent on what the Local Fire Chief will them stock for quantities.
Only time i was buying ammo at walmart was for the 4 pack shotshell target loads and WWB cheap stuff and ZQi was practically giving thier ammo away through walmart
