I already have a copy of the 2nd edition of this book (I paid $$$ for it). It is a great book with beautiful visual examples that clearly illustrate the concepts.
Today only, from dealfuel.
EDIT:
it seems that this deal is still being offered today. I've updated the expiry date accordingly, but it will no doubt end today so be quick!
EDIT 2:
Deal still appears to be going. Removed "TODAY ONLY" from the title.
got a direct link? :)
