http://www.stonyfield.com/ These coupons expire quickly (2 weeks or so), so only print the ones that you’ll use soon. They also have a print limit, so print them sparingly.
http://www.energizer.com/ They usually have a coupon for regular batteries and rechargeable. Using rechargeable is not only green, but it saves you green. I have charged my batteries so many times and I can't remember the last time I bought alkaline.
Now go save some green, while you are saving the planet.
