From an American viewpoint at least, this is actually very reasonably priced. Paying < $20 for a session of medical services is essentially unheard of. I paid $30 as copay for PT every two weeks with rather nice insurance, and every time I walk into a doctor's office it's _at least_ $30.
I have never pursued therapy but I'm sure it would be a minimum of $30 per session with insurance, if not more.
Not to say it couldn't be better, but at first glance this is a _great_ improvement from the status quo.
