Karen De Costner has done a few posts where she tabulates the costs of her paleo meals. For a family of 4 she compares the cost of her meals to going out to Arby's for roast beef and cheddar sandwiches. And she compares both the supermarket staples and the fancy organic and grass fed staples. They always come out to more food, more nutrition and less cost compared to the fast food.
