I know you love coupons and you love being green. Coupon Sherpa is a mobile coupon application for your iphone. And better yet, Coupon Sherpa is FREE in the App Store until Earth Day! According to a report by the nonprofit group ForestEthics, '??mail advertisements create 51.5 million metric tons of greenhouse gases each year.'? That number is equivalent to the emissions produced by heating about 13 million houses or mowing more than 20 billion lawns.
I don't have an iphone, so I'd love to hear from someone if this actually works. After Friday (4/23) this goes back to $9.95.
