I’m constantly amazed at how cheap milk is in the grocery store. A gallon of Great Value 1% milk is $2.77 now. That seems low for what you are getting (a gallon of protein rich fluid milked from a cow and transported to you). How much profit could be left? I’ve heard that grocery stores sell milk for less than they buy it for just to get you into the store, because they know you will buy other things. I haven’t checked the truthfulness of that statement though.

A link about the margins implies that may be technically untrue but I don’t know enough about the grocery business to say.
