Just wanted to say thanks for this thread. I never heard of this app until this thread popped up on a search this morning. I went to my local Walmart this morning around 8:30 looking for any 22LR.......none to be found. I found out about the app from this thread when I got home a little while later, downloaded it, and lo-and-behold! They showed some Remington 50packs in stock. So, I went back, and they had just stocked it in the case. I would have never thought to go check again today, but I'm glad I listened to the app. It's been slim pickings around here, especially for 22LR.(If I'm really lucky, they'll have some left tomorrow so I can get 3 more!)
