I recently purchased a grocery bag from a grocery store for a few dollars. The clerk rang up the rest of my items and placed them in the bag and informed me I get a few cents off for using the bag, which surprised me. Come to find out, a lot of grocery stores are doing the same and in the end, everyone wins. Also, I made a commitment that if I go to any store and purchase something small that I can hand carry, I will deny a bag. It saves the store money and it saves the earth one less bag in a landfill. That was my effort in going green.
