Rent you textbooks? Why not...

Have you ever thought about renting your textbooks. You can make more money if you rent them instead of selling them... You can do that on www.cool-rent.com. It is up to you...
For example: lets say you think that you can take $50 when you sell your textbook. Then you can make it like that - the deposit plus the price you take for the rental to be equal to $50 (less or more - that depends on you). And when the book is returned you can return the deposit to the other person.
It is that easy!
