I've seen this posted in a lot of places - lots of buzz about it -
Green Zebra.
It's a coupon book for all things green and earth friendly in SF. Kind
of cool, especially since it gives you a good idea of where to start
looking for these kinds of businesses.
I just entered today to win a free one off FunCheapSF,
but I might buy one anyway. I saw them for sale at href="http://www.colehardware.com/">Cole Hardware. There
are lots of coupons for Yoga Studios, which is good if you're into
Yoga. I'm not... yet. And there seemed to be a good number for food
establishments - always a good thing. And, if you're
building/remodeling there were interesting listings for that too.
