The mill is forced to produce it as 37 in. wide. Because it takes the same line time to produce a 37-in. coil as a 72-in. coil the rolling speed does not change, the mill productivity drastically decreases. There is a good chance the mill will charge you a width extra in your price to account for the mills productivity hit.
