This is not something I can agree with.
I said: Don't audition anything you are not willing to purchase.
Not the best choice of words, please allow me to re-phrase/explain: I meant price range. It's so easy to get a broad sense of what is appealing from a personal cost / benefit analysis before going in. Then look around, ask some questions, and make an appointment to come back and dive deeper.
If it goes well, make a deal.
