Wal-mart sells primers?

I've noticed at Wal-mart that different stores will have different brands currently in stock. I guess I'm just trying to say that in some areas, the cheap stuff is always sold out. I'm trying to remember if I've seen .40 for cheaper than $17 at Wally World yet.

I thought Gander was competitively priced on self defense ammo, but it's hard for me to tell because I've purchased exactly two boxes of self defense ammo in my life.
