Site allows you to rent books for a reduced price for varying durations. It’s a novel approach. I like it. At the end of your rental period, if you don’t want to return your books you’re allowed to purchase them, and your previously-paid rental fee is put towards the cost. The downside of the rental thing, in my view, is that you have to keep the book in “like new” condition according to the site, so you always have to worry about fraying pages. You’d probably have to put on one of those paper-bag slip covers like in high school. Also, the site does buybacks and commits to paying you the most for your used books out of anyone on the Web. It requests that if you find another site willing to pay you more for your books, that you send them an email. They will pay you 10 percent more. It’s still a pretty new site, and concept.
