Someone correct me if I'm wrong, but I think there is a list of treatments and prices on the GF FAQ right here on these boards.

I used the Spa in June for a manicure/pedicure (each were about $53) and a deluxe facial (I think it was around $120). The facial was one of the best things I've ever done for myself....very relaxing and my skin felt amazing for the next 3-4 days!
