There seems to be only about 2 days a months that Wall Mart, K-Mart, Meijers, etc.. has any stock on .45's. At least that's the way it is around here. They sell out almost before they sit on the shelves, and when you do find them, you are limited to 1 box per purchase.
Endless supply of 9mm and .40's, but the spot on the shelf for .45's are usually empty.
On a somewhat related note:
Cook county (Chicago) Board president is pushing for a
nickel tax on EVERY bullet sold. Ouch.
