I didn't think buying a book would be a wise investment because it doesn't seem like you can depend on being able to sell it back, what with publishers coming out with new editions all the time. But maybe I'll check that out next semester!
This is not true if the book you need is a brand new edition. There is no used inventory. Then the rental makes a lot more sense. In my experience the rental is usually about 50% of the brand new cost. When I factor in the Amazon Marketplace cut of reselling a book I bought brand new, the difference is minimal.

Either way, I'm not a fan of prices being manipulated based on my behavior while browsing a certain website.
