Just to add to the reference mix, I stopped by Walmart this morning and they had no pistol ammo on the shelf except for several boxes of .25 cal.
The counter girl mentioned, though, that they had just gotten in two cases of 9mm WWB FMJ and one case of .45 WWB FMJ. That's it.
The 9mm was going for $19.99 for a 100 round box.
The girl told me that it would all be gone by 10:am (I was there at 8:am) because she had a list of people to call when it came in.
