Before hybrid engines and solar panels, going green meant eating too many corn dogs and then riding the Tilt-A-Whirl. Exercise another green feeling with today's Groupon: for $25, you get $50 worth of eco-friendly school and office supplies from O'Bon.

O'Bon's online stationery emporium slings environmentally responsible school and office supplies to paperless patrons. Choose from colorful creations, such as the pack of 10 wildlife pencils, featuring tightly wrapped recycled newspaper around high-quality graphite, printed with different animal designs ($5.60). The emerald spiral journal, made entirely from sugar-cane paper, soy-based inks, and 100% recycled card-stock covers, offers ample space for drafting Golden Girls fan letters ($4), and a pack of 12 colored pencils provides the means for doodling realistic landscapes ($6). Practicing Picassos can employ the L'Artiste art pencils, including a wide range of high-quality graphite grades from ultra-hard 2H to ultra-soft 8B, which mark lines up to eight times darker than the spooky bottom of a clothes hamper ($13).
