Mail 5 clean Target plastic bags in by 11/30 in the People magazine cover OR in an 8x11 envelope, and in January Target will mail you a coupon for a free Target retote. (reusable bag)
Free is always for me :) I've really enjoyed my reusable bags from Whole Foods and Wal-Mart. They hold more groceries than plastic bags and I truely do feel like I'm helping the environment. I started keeping the bags in my trunk so I don't forget to use them.
