Eh, I've tried that many many times for many different things, and I've never been able to get an exact price quote beforehand. The response is always "you need to talk with so-and-so" who is always someone or something else. It's a maze of runarounds, with no one willing to commit to anything in particular.

It's one of the many things broken about the US healthcare system. In no other market would a seller be able to get away with not providing a contractual quote before the service is provided.
