I want everyone to know that if you like to buy ammo at Wal-Mart that the employees are cheating by putting away a secret stash of ammunition under their register at the ammo counter for their own purchase. When I asked the clerk if I could buy the ammo under the counter he acted like it didn't exist....even though I saw more than there was on the shelf. 9mm, .45, .40 S&W, 7.62x39, .223...all popular calibers and meanwhile there is only odd rifle calibers on the shelf in limited numbers. I witnessed the individual open cases of ammo and take boxes out and place them into a secret stash below the counter under the register. Next time I want ammo, I will talk to a manager and ask to pick from the secret stash when there is none on the shelf. I am sure your local Wal-Mart employees are doing the same thing.
