Our local Wal-Mart is now carrying Augason Farms products. Sealed #10 cans of powdered eggs, margarine powder, freeze dried veggies, flour, whole meal variety packs, as well as buckets of wheat,oats, etc, etc. Some items have a advertised shelf life of up to twenty five years. Augason Farms is headquartered in Utah. I don't know if they provide to the LDS members or not but those folks have a pretty good handle on storage foods and prepping. Anyway, just a heads up for my fellow preppers. Check it out, the prices seem resonable enough to me.
My case in point about prepping in general lies with personal experience. Over the years, I have had to have back surgery, and later on a broken/dislocated wrist. Both time yielded weeks of not working. It was very comforting to know that my family had the food to get by already in the pantry. We did not ever have to decide if we were to make a house payment, buy gas, or keep the lights on, instead of grocery shopping. Take care all.
