> They will never, ever do a deal that they aren't completely happy with
There was an episode of This American Life about car dealerships that everyone here should really listen to [1].
In that episode they did close deals where they were losing money, but hoping it would make them meet their monthly sales goal (set by the supplier), which would result in a bonus that would put them in the black.
