What about visiting your local library? They will get anything in for you even if they do not have it in stock.....and.....in case you worry about getting fines for not getting the books back in time.....you can renew online in most areas now. Certainly a cheaper option than buying when you are not sure about a book. It costs nothing to join your local library.....most of them have dvds to loan these days too!! (You can see I have been a library assistant!!?)
