Saving money on milk

To save money on buying so much milk here I use powdered milk and make my own. This saves us alot. I genereally fix about 2 gallons a week. There are six of us and 3 are kids so we go through alot of milk. The milk is fat free but tastes better than skim. The kids get their fat through other sources. I fry things for them , they eat alot of pizza and other fatty type foods. I use olive oil and canola so the fats that they are getting are the healthier kinds.
