Not sure where in the world you are, but Sprouts in the US sells milk in glass bottles. You pay a fee, and you get that back when you return the glass bottle the next time you come in to buy more milk.
It's not delivery, but it's a whole lot better for the world than more plastic.
Danzeisen Dairy is available in Phoenix at various grocery stores. I do wonder what the fuel consequences are for the additional weight. It would be ironic if the fuel consequences are more than the plastic they could be in.
