Get a free reusable bag made from recyclable plastic bottles at Target on April 18, 2010, the first day of Earth Week. You have to make a purchase, but if you coupon-stack, you may be able to get your purchase and bag for free!
Target is giving away 1.5 million of the bags, so there will be a lot on hand at every store. However, if you really want this free bag, I would arrive within an hour or two of opening. This freebie is not available online.
Caveats: one per guest, no rain checks.
