It's on Amazon for £151. This compares with £65 for the 8th edition. Anyone know why it's so much more?Hull lists the differences here: New features in 9th editionMain things seems to be OIS discounting, OTC regulations and a better version of derivagem

Paul: Thanks for your reply - I'm very pleased to hear your stance on morality. On the strength of that I'll definitely be ordering PWoQF 2nd edition as soon as I'm back from holiday and have found the best price. Thanks

I'm thinking of getting PWoQF, but as the 2nd edition was published back in 2006, wondered if it was worth waiting for the 3rd edition to come out. Does anyone know of any plans for a 3rd edition please?
