I don't have a credit card either
Edit: Well, I can buy the book for you, and send it to UK... will just have to head for a bookstore and no credit card is needed
Edit 2: I've found my favorite online store, which needs Credit Card (I'll have to ask my mother if she would let me use hers), has the service of delivering books overseas...the total fee would be 616 TWD which is about 10.5 Pounds
Edit 3: Are you really going to read that Chinese book?
