I have bought quite a bit from walmart.com. They have Augason Farms and Mountain House for the cheapest prices I have found. Many of the things that I have seen mentioned are available there. What I really like is that it is free shipping for over $50.00 and delivered by Fed Ex to my front door.
Yes, Walmart online has been a good source of reasonable priced things. I tend to stock along the lines of long term basics, and then the stuff that we eat all the time. I do stock some convenience and processed food items for emergencies and busy times.
I do have some of the Auguson Farms stuff, but we tend to eat mostly whole foods, so I don’t have a lot of dehydrated entrees etc. I do dehydrate things like celery, carrots, peppers, potatoes, etc. and it’s cheaper than buying it from other sources, and we use it, so it doesn’t just sit on the shelf.
I like to have some long term stuff like the LDS and Auguson Farms stuff, because we don’t have to rotate it every year or two or three.
