It seems like all of the forums I read direct me to do my own dehydrating, so I am a little intimidated to ask what is probably a newbie question. Why dehydrate the food yourself when there are so many places you can buy it for cheap. For example, I recently found Emergency Dehydrated Food, emergency food, disaster food, preparedness food, storage food, and survival food. which offers varieties of fully dehydrated meals. It tastes as good as Hamburger Helper and I got one pale of 500 meals for $65. It just seems like a ton of work to do it yourself when you can buy it that inexpensively. Thoughts?
