I would not consider myself an expert in environmental issues or even a tree hugger, but I do what I can ~ when I can do it! I just love love love these earth friendly bags from Costco. I purchased three for just over $1 each. The deal was even more sweetened when I realized I won't have to make many little trips back and forth from my car when carrying in my goods. If you happen to run into me at Target, Albertsons, anywhere shopping . . .look for my green. GO GREEN!
