I love Whole Foods because they really encourage shoppers to carry reusable bags. If you happen to forget to bring your own, they have bags (made from recycled water bottles) for sale for $0.99. But if you don't wish to pay, they have these paper bags. This holiday version is particularly cute!
Even Martha Stewart will agree that this is a "good thing".
Suggest ways to reuse it by writing on the tag: "Reuse this bag for your jewelry" or "Reuse this bag for your school lunch".
