Next cheapest is £28.99 @ HMV so that's a £19 saving. Not seen it (yet) myself but this series is supposed to be rather good action/comedy. The series comes on 7 discs constituting around 650 mins of anime goodness.
"In Japan, a novelist is dealing with writer's block after her friend goes missing. In Hong Kong, three sisters who are masters in the use of paper, run their own detective agency. When these people are brought together a bond greater than blood is formed; a bond that will be sorely tested by the evil powers intent on taking over the world. Join Anita, Maggie, Michelle, and Nenene as they travel the globe in order to save the world from the evil mastermind, Mr. Carpenter. Of course, this is if they can find the time to put down the books they are reading?"
