My CDC is absolutely lovely. I didn't pay a initial consultation/joining fee, and pay £35 per week for shakes (powder), £37 per week for all tetras/bars and £6 for flavourings.
That said, I can understand an initial consultation fee -- providing you get an in depth introduction to CD, photos, etc etc -- and wouldn't have objected had she charged me that. I travel to her, so she doesn't charge travel expenses but, again, I could appreciate being charged a SMALL fee for that had it happened.
Up front fee for the following week I think is a bit off, though.
My ongoing support is fab too -- guess I'm lucky on that score!
