Very cheap. For 50 cents a pound I can buy a 10 pack of chicken legs for 2.50. I make sure its as close to $2.50 as it can get because then I know each leg is .5pounds and I don't have to do any dividing or measuring at home. This is her main meat, costing $15 per month. Organs are cheap. Its less than a dollar for a pound of some other meat I can split into two days. An egg costs 3 cents a piece now and again. I don't do yogurt because Autumn has always gotten regular milk daily, but a big bucket of plain would be a dollar. Veggies and nuts are grated from the human supply at home on occasion. Flax seed, ground, was $1.38 for a big box that should last over a month. So basically it costs me about $20 per month.
