Have you ever passed on registering for a class that you need for your degree, simply because you can't afford the text book? I have. That's why I decided to start a site, designed specifically for books used at Great Basin College, so students can get the texts they need without spending hundreds.
The texts listed are available for purchase for a mere $10, even though I've spent far more on them. If you have a text you've used at GBC, you can trade it in for another text at no cost. If we all help one another, we can save a great deal of money while helping others in the same situation.
Why spend as much on a text book as you do for a course?
