WeightWatchers Online Plan - confused, how much is it per month?

[plinkduet]

Is anyone doing this plan? I'm at registration stage but I can't work out how much it costs! It seems to say it's £10.95 a month or something but on registering it says £40 a month :(

Can anyone tell me how much they charged for initial registration and then monthly cost?

Thankyou

When I did it I paid 35 I think for the first three months on some sort of offer a couple of weeks ago - lost 7 pounds so far wooooo hooooo! So it must be for the first three months
