I think it used to be cheaper ... what I ended up with was a copy of the textbook.
I ended up doing the interview because both of my bosses were busy with other stuff and they didn't want to bother with it.
Interesting side story ... one of my friends is a professor of Social Work, and she decided to use the textbook for one of her classes. I got an excited call from her after she had read the chapter, saying that she read it and at first thought "no, it can't be that wolf," but checked the footnotes section and saw that it was.
