renting a textbook for your school can be a great way of saving  

Chegg is really cheap.

That is a great way to save money. If you buy the textbook, you could just sell it to another student when your done with it.

OR better yet you could be one of the people renting them out to students. You could probably make more money than the textbook is even worth.

I do think that this could really be a really good way of saving money, especially since buying textbooks can be so expensive. If it works well for students, then that's really great.

While I completely agree that most of the time buying your textbooks can be far too expensive (especially if you're studying anything to do with computers), a website that my mum recommended to me was bookbutler.com, obviously its still going to be more expensive than renting, but sometimes I've found second hand copies of my textbooks at a couple pounds (plus p+p of course), which is nice as I'm one of those people who likes to make notes in my textbook to help me when it comes to revision time.

well i think in this country we dont have any of these kind of services. we can borrow one in the library but its not worth it especially with the time limit you have on those books.

i usually buy 2nd hand books. just like you i cant really buy some of the books that i want. just one book that i want will cost more than $100 and i need a lot of books.
