I have been waiting for a long time for this book to come out.
Cheapest I could find online was £9.49.
Walked into WHSmith and was able to acquire for £8.99.
I know you can get quidco with online sites and WHSmith are offering additional discounts next week. But i'm impatient and would have bought this even earlier had I not been in the states where the book is not realised until January
