Josh Dorfman and Sundance speak to penny pinchers and the generally confused.

thedailygreen: What are the best ways to be green and save money?

Josh Dorfman: The Internet is a great way to start. Sites like chegg.com rent college books to students, saving 65-85% of what textbooks cost, while reducing environmental impact. They even include a prepaid shipping box to send books back when done. We're starting to see this model extend to a lot of businesses: trading and swapping sites like swapstyle.com, where you can update your wardrobe without buying anything new; paperbackswap.com, and CD/DVD trading sites. Or Zipcar, a car sharing service that makes it possible to never own a car.
