Cordele had 100 round packs of .40 and .45. .40's were $38 and .45's were $40.77. Sales person confirmed that ammo hits the shelves as soon as it leaves the truck. She hasn't seen any spam cans, but sold a 420 federal can Wednesday.
Haven't of Wally world doing this, but an acquaintance of mine said he was in Columbus at a shop and they would only sell him one box. It didn't matter if it was a 5 round buckshot or 100 round box.
I bought two of the federal 100 round bulk packs this morning for $34.95. The guy told me they had a lot of ammo .223 and 7.62 they didn't have room for. They had an ass load of .40 and were almost completely out of .22.
