If I could give no stars I would. I received a completely different book to that I ordered despite several confirmatory emails. This does seem to be a common occurrence with this web site from the comments I have seen since. Their customer service is worse than useless as I still haven't received a refund. They wanted me to abuse the postal service to return the book and when I refused they insisted that I had to return it at my expense. I didn't even order the damn book! I will never go near them again and advise anyone else to avoid them.
