Since you have to have a grade A dairy license in Ohio to sell milk, I don't. I think people sell it for pet use but even that is frowned upon in Ohio and many people don't advertise. For pet around here, people are charging $6-$8 per gallon.
The goat dairy down the road from me sells pasteurized milk for $8 per gallon. I thought I'd sell a little to close friends for the same amount. But then I got really good at cheesemaking. We need more goats!
You need a permit to sell it in PA. I really don't have enough to sell anyhow, I am with everyone else - the cheese is yummy and my family is always asking for more.
You have to have a license in Arizona to sell raw milk. The stuff that the grocery store carries is about $4 a pint for pasteurized, bucky tasting gross stuff. Seriously, what do they do to that stuff?!
I have a few close friends who get milk or cheese from me if I have extra, I don't sell it, but gladly accept "donations" in the form of money, feed, or produce if they feel they need to give me something for it.
