But yesterday I was surfing around the site and noticed they have a new category of rewards -- "Eco-Friendly" products. They range from solar backpacks to carbon offsets to compact fluorescent light bulbs.

Separately, I bought myself some reusable batteries and did the same for The Green Mom when I bought her a new digital camera for her birthday. All this was prompted by my shock and awe when I tried to buy four AA batteries for my camera while in California recently. Every place I looked was asking $4, but four rechargeable batteries with a charger is only about $20 -- and those are allegedly good for hundreds of charges. In this case, I'm doing the right thing for the environment by coincidence -- my financial interests and my climate consumerism are one and the same.
