My recent experience has been that I can find .22 at most gun stores, and the price is usually $5/50 for the lower end stuff and $10/50 for the higher end. Sometimes, they are out of the $5/50, but it usually surfaces in a week or two.
I think what most of us miss/can't find are the bulk boxes and bricks for $15 to $20 range. I haven't seen those (at that price) in a store in forever. However, I've been able to get them from Academy (online) about once a month or once every two months. They have the 333 bulk box for $18 and the 500 round thunderbolts for $25, just have to be quick when they are in stock to get them order. They offer free shipping for orders over $25, and they limit you to one box per order, so I usually order an extra box of .223 or .308 or something to get to the minimum order.
I'm sure someday we will get back to .22s in Wal-Mart (regularly), but it may still be a while.
Good luck and take care.
