I was introduced to an online book store by Jia called the Book Depository. It is based in the UK and offers free delivery world-wide and the books are extremely cheap! I ordered a book called 'Cross Stitch' by Diana Gabaldon for only $9AUD on the 4th of March and it just arrived today! So the delivery is fairly quick, about a week's wait. The books in a good condition, pretty happy with my purchase.
