Query: Great book, shame about the postage price

I bought this book, I live in the UK. It did not tell me how much the postage would be when I purchased it, just told me what the book would cost in US$. When I received an email confirming this book would cost 37 GBP I nearly fell over. It also wouldn't let me cancel the item even though it hadn't been dispatched. In the shop it only costs 8.99 so why would I want to spend a fortune on a book I can get for a fraction of the cost!!
