Was in BassPro in Ankeny, IA the other day, and they had several 30-rd PMags on the rack. $16.99 IIRC. Watched two of them disappear. (Not me, I've got plenty).
OTOH, no .22LR ammo, and I heard the clerk say they'd just gotten a shipment in that morning. The customer said, "Was probably gone in half an hour." The clerk said, "No, two minutes."
Fortunately, I've still got a couple of bricks of CCI left.
