Hiya,
It definitely depends on your LLC - according to mine, the £66 you pay weekly is for your packs and that is why the cost goes down once you go into RtM. A couple of the girls in our foundation group had loads of packs left over and our LLC let them not buy any for a week (this was during foundation!!) and use the ones they had at home. They didn't pay anything for that week but were still allowed to attend the group meeting and have the counselling. Today at our meeting one of the girls again has packs left over so the LLC has allowed her to only buy 7 bars this week and use the leftover packs for the rest of it. Our LLC is great with things like that, I guess it's a bit of a case of luck of the draw....
I have about 23 spare packs sitting at home... if it gets to 28, I will definitely ask my LLC if I can swap flavours for a week rather than buying additional packs xxx
