Buy used college textbooks

If you are a student who is getting ready to go back to college there are some ways to save a dime.  I would not suggest paying full price for textbooks.  Usually you can find out ahead of time what books you will be using for the class.  If that is the case, go online and buy the books used.  Some great places to buy used textbooks are Half.com and Amazon.  When you are done with the books you sell them as well.  If you buy new you might end up paying 75% more than if you spent a little time and bought them used online.
