Whoa, $18/gal is a lot. I pay half that for a gallon of raw A2A2 milk.
Look for a farm and buy it directly from them or hit up farmers markets. Might make for a good road trip.
I get mine from a farm 1.5 hours away, called Dutch Meadows. Luckily they deliver to where I live.
Both they and Amos Miller’s farm ship product but I’m not sure if/how dairy is shipped across the country.
