Hi there
I was asked to cover the cash desk last night at class and 2 people purchased countdowns and they both got the book, and yes it is £24.75 for the 6 week coundown.
I would highly recommend buying one, I have had 3 since the beginning of the year. 2 12 week ones and this time a 6 week one. It is so much easier without having to make sure you have the money to go to class. Plus it makes you go to class even if you know you haven't been good as you have already paid for it.
