My funniest time purchasing ammo from Walmart was when I was traveling from one city to back home and stopped in for some washer fluid which was on sale at the time. Being a gun guy, I always wander down to the ammo section to check it out. Well low and behold they had boxes of Winchester 7.5 in 12g listed at $2.50 a box. I know the regular price is usually around 7 or 8 bucks so I called an employee over and asked her to verify the price. She punched it into her price gun and said "Yup, that's the right price" I said I would take some and she called the employee with the keys to help me. Well I waited and waited and eventually he came round and I told him which one I wanted and he asked just one and I told him all of them. Well he had to go and get a cart to put them all in and started to pull them off the shelf. I ended up grabbing 28 boxes total and when I got back to my home city I decided to check my local Walmart in case it was the same price there. It was the regular price at 8 bucks a box and when I asked the manager if they would price match another store, he said he would. I showed him the receipt from the other store and he said wow that's a low price. So I ended up grabbing all the shells there too and ended up with around 60 boxes between the two stores for $2.50 a box. I've never seen anything like that since.
