Does anyone use EcoPerks?

Like I mentioned in another thread, I am extremely interested in social media and Web 2.0. The marketing company I work for is currently doing a campaign for the environmental online community, EcoPerks. Has anyone heard of it or does anyone use it?

EcoPerks encourages and supports green efforts of the community. They also donate 1% of every transaction to organizations that are committed to helping the environment.

We are currently working on their Paperless promotion. You can earn EcoPoints by signing up at: http://www.ecoperks.com/paperless.php. I figured I would share because it’s a cool, eco-friendly site.
