How can I save money on textbook costs?

​You could try purchasing second hand either from students who have placed ads on the student notice board outside the Bookshop or from websites such as textbookexchange.com. Be aware though - you may not be buying the correct edition. The lecturer may have decided to go with a different edition, i.e. 5th versus 6th. You could be purchasing a U.S. edition when the Australian is required. Is there a CD? In most cases if the CD has been used by the previous owner it is unlikely you will be able to download on your own PC. CDs are usually a once only download or to be used on one PC only. The text may include questions, activities etc which may have already been written in or highlighted.
