I don't think I've ever bought a cookbook at it's original sale price; I find it much more satisfying to buy them cheap. Some great places are car boot sales (as low as 10p), charity shops and second hand book shops. Even WH Smiths can have some good offers on. I picked up Small Adventures in Food by James Ramsden for £1.99 from a cheap shop and immediately started reading it on the train home.
