Don't know if it's true, but heard yesterday afternoon on WORD radio that Walmart in Simpsonville is supposed to get a shipment of ammo this morning. A trucker called in and said it's mostly .223. As I said, I don't know if it's true, just heard it.
FYI - Just there, and they had the following: 9mm Luger 115g 50/pack @ $11.99 (maybe 30 - 40 boxes). .40 caliber 250/pack @ 99.99 (maybe 4 cases), and a couple of .45 caliber 250/pack, but I didn't check the price. Even a few .223
