We have stocked up and could probably go 3 to 4 months if need be. I used to be able to buy powdered milk in large boxes. Can't even find small ones today. Went in to Harris teeter today and no organic milk, just a sign saying Due to severe summer weather we are currently on a "Nationwide organic milk allocation with most brands". Wow! I guess organic milk cows don't eat the same junk food as milk cows do because there was plenty of regular milk. I switched to organic because I have become "lactose intolerant" in my senior years. However, organic milk does not bother me at all. Strange? Oh well.
