You can buy 275 emergency food servings with a 2o year shelf life from Costco for about $80. So assuming 3 meals a day for one year, it would cost just $320 for a full years supply of food. That's less than a dollar a day. Or about 10 minutes work at minimum wage. Or to put it another way.... Work just 1 week at minimum wage and you can afford a years supply of food.
