I bought this book from amazon as it was required for my university course. However, when it arrived, it was battered, dirty and pages dog-eared. I thought it may have got damaged in transit and as i had an assessed piece of work due I decided to keep it. Today I entered the CD into my laptop and it did not work. Turning it over, I found that the CD was scratched and dirty. It then became obvious to me that amazon had sold me a used bad condition to me. It is not good enough when amazon claim to sell books on a "new" basis. Do not make the same mistake and spend the extra few pounds buying a truly "new" book from waterstones or blackwells. Disappointing.
