I'm sure many of us are going back to college so why not get a cheap textbook post going???
I have used AddAll for the past 2 years to find the cheapest college textbooks. Sometimes it is cheaper to buy it overseas (say, Amazon.co.uk) than it is to purchase in the U.S. AddAll will help you figure it out...
I'm sure many of you have used other services, maybe you can post your experiences here.....
