I stopped at an Academy Sports and Outdoors store tonight, and at the customer service desk they had 50-count boxes of .22 LR in stock for $2.19 each.
They also had some 9mm and several different brands of .45 acp in 50-count boxes.
Saturday shoppers hadn't cleaned 'em out as of 7:00pm. This is the first time I've seen standard .22 LR on a shelf since before Christmas. I take this as a sign supply may be catching up with demand.
