Grocery store mark-ups are complicated, and involve a lot of psychology.
  Often they'll have "loss leaders" that they don't make any money on,
because they know once you're in the store you'll buy some other stuff
that's heavily marked up.  Commonly needed items like milk are almost
always put in an inconvenient spot in the back of the store so you'll
walk past other aisles and pick up stuff on the way.
