That's good to know, thanks Fiverings.
I'm never quite sure how the book chart works, as most shops tend to do their own (often influenced by publishers paying for high profile spots), but I know the Times list sticks to actual sales.
I'd guessed it must be doing fairly well as there weren't any in my local Sainsburys, nor were there any copies left at the WH Smiths at the train station. Meanwhile, there were huge displays filled with the David Beckham book.
More promotion for the book on this morning's Andrew Marr show, complete with a few good clips from the final, and more. It's on the iPlayer at about 25 minutes in, but if I've done it right, this link should take you straight to the relevant bit. http://www.bbc.co.uk/i/b03kg9yn/?t=25m32s
