About a month ago my local corner grocery store started stocking Seventh Generation laundry products. I was so pleased by the new addition that I thanked the manager after my first purchase. Yesterday on my way home I stopped in to pick up some groceries and the manager spotted me. He was very excited to show me that he ordered an eco-friendly line of cleaning products and reusable grocery bags.
It is really amazing what a little positive feedback can do. Next time you are at your local store and you spot something they are doing that is helping the environment, just point it out and say "thank you". Chances are the manager will remember this when ordering new products for the store.
