I don't think .22LR is readily available anywhere, unless you want to buy from the scalpers @ 15c/round. Our local Walmart gets deliveries every Saturday, so the scalpers hang around until the truck arrives and then they line up to buy everything that came in. I talked to the guy in the sporting goods dept, and he said that it's always the same guys...
BTW, this was kind of funny: When the ammo situation was really bad, the scalpers were selling the cheapest bulk pack .223 for $1.50/round. I happened to ask the guy in a sporting goods store if he had any .223, and he said: "Yeah, we have plenty of Hornady V-Max but it's kind of expensive, $19 for a box of 20". In other words, I could buy premium ammo for less than the bottom feeder stuff.
