For a regular wrap (at least in my area) it's $139 and goes up from there for the different types.
They explain basically what is in the minerals, and they did tell me that everything was food pure. It's a carefully guarded secret I guess, so I think you'd be out of luck to know absolutely everything. I bet even their workers have no idea what it exactly contains.
It's actually pretty hysterical to be wrapped up tight like a mummy and have to jump on a rebounder for an hour. You have to keep your sense of humor.
