As I live alone, buying milk was almost a waste for me. What I do now when I buy milk whether its a quart or gallon, I'll put 2 cups into a freezer container in as many containers I have available and put them into the freezer for cooking at a later date. I have an Impossible pie I make up quite often and it takes 2 cups so its already measured out for me. I don't know how well it works for regular drinking once its been frozen but for baking/cookings its great.
