C.S.
I am not sure it is the exact same thing, but I paid about $18 for a book which was emailed to me and I had to print myself. I thought it was a bunch of nonsense written by your average Joe and I didn't follow it. While $18 was not a lot, I think I was more annoyed with the unbound mess of papers which ended up everywhere.
My daughter cried on the potty, so I waited a few months and then things worked out wonderful. Once she was on a roll, she never stopped.
