I pay £2.20 for each tetra and bar, I think the packets are slightly cheaper. CDC's can charge different amounts though so you will find there are differences depending on who your counsellor is. Mine works out around £46 per week.
Hiya. I pay 1.85 a shakes/porridge/soups. And 2.00 for ready made shakes and bars.
I only started on Friday and had 2 days off due to been in hospital but loving this diet. Really worth a try. Good luck
