Rent your books instead of buying them, and save the environment
Chegg.com is a service that may be a dream come true if you are a college student in the United States. They basically offer you a rental service for your college books. It’s a simple process. You can search for the books that you need and then place an order for their rental. The book is shipped to you, and you are welcome to use it. They even allow you to highlight in the books that are sent to you (but not write). Once your term is over, a pre-paid shipping pack is sent to you to return your book back to Chegg.
