He's probably been given orders to ration ammo. Most retailers are doing that now.
Yes they are, but if the OP is repeating everything exactly how it happened.... that's not rationing.....it's an employee being a stinking liar who appears to be trying to cheat the system.
The system being they are a retail chain and ALL of their products should be out for sale to the public at the corporate set price....first come first serve.
Or.....what bumnote said. I do my absolute BEST to only use walmart as a LAST resort shopping center for anything. I just went and paid almost $7 more for a set of dust covered sling swivels at a local bait and tackle shop, just to not buy them at walmart.
