How to breech a topic with provider?

When a well known, well reviewed provider doesn’t have a website with published rates, and you aren't supposed to discuss rates while scheduling an appointment, how do you find out rates to insure you come prepared?

If she’s well known and well reviewed, PM a fellow monger who saw her recently.

After you get screened and appointment set, ask what the expected donation is. On p411, rates are usually posted.
