I'm on vacation at Bethany Beach MD and, as I always do, went to check prices of ammo at Walmart. I asked the manager about .22 and he told me starting Monday (Aug 22nd 2016) that Walmart is taking them out of the system. Not sure is this is US wide but thought I would give the heads up.
After church today, my family stopped by the local Wal-Mart on the way home. As usual, I scanned the ammo shelves for anything worthwhile. Low and behold they actually had .223, along with several other in-demand calibers. I purchased 3 boxes as per the limit and went in search of my wife...
Things seem to be easing a bit.
500 rds of Federal 9mm @ $9.47/box left about 500 on the shelf,had more in back.
1000 rds .40 S&W $13.5/box,more in back
550 rds .22lr $17/box
winchester .223 $20/box
