Sure. If there was another place to buy a better door at. But if that door manufacturer's the only one that makes doors, if the door installer and door technicians all tell you that they can't or won't make another door for you, then you just deal. Maybe crank up the prices a bit to try to mitigate your 10% shortfalls.
The place where a business looks at that problem and sees money being left on the table that it can't live without and that it has no other way of making up for... that is a very narrow stretch, and only very marginal businesses live there.
