Nice deal spotted at Home Bargains in Edgeley, Stockport. I can't confirm if this deal is nationwide but I imagine it is. 128 pages in the annual, and some good information/quizzes inside. It mostly covers seasons 1-3 of the show but also has some information about seasons 4-7 and pretty good character profiles, or information about the weapons/gadgets featured in the show.
You can't go wrong at that price.
