Yes the bella magazine has an offer on so you just pay the first week fee (4.95) otherwise it is 14.95 to join a group normally. I think there is a refural thing on at the mo too (although that may have ended now, not sure)
Referral is still on so a member gets a free week if they bring a friend or two for two friends etc. think it runs till the end of July. Oh and if you buy a countdown there's money off too, either 6 weeks (1 week free) or 12 weeks (2 weeks free). I got the 12 week one. Only thing is you need to book holidays in when you buy it or you lose those weeks if you don't go.
