This is our most robust supply package that we offer. This works for one person for four years or four people for one year. Our four year food supply comes with a balanced and nutritious variety of 4800 servings. We have studied and researched exactly what we feel will be needed in an emergency or disaster situation when stress levels could be running high and nutrition and food intake is of utmost importance. Like all Eat Tomorrow Foods, our three year supply has a 25 year shelf life and is GMO free, Soy Free and Gluten Free.
