Not a month goes by without a book to big screen adaptation these days so the rush to read the tome that inspired the movie is well and truly on.

Of course, as soon as a film project gets the green light the price of the book tends to soar. Sure won’t they even release special tie-in editions to keep the cash rolling in?

Never fear though, you could come across any of these sought after selections for a fraction of the price in your local charity shop.
