I've been intending to mention this since Earth Day; but was reminded again when my wife returned from a conference and some of these were in her "goodie bag". Reuseable cloth grocery bags.
Jodi had been using them for several months now. And on Earth Day, local television did a story on the bags stating that stores (such as Meijer - above on left - a Michigan-based grocery chain) was having trouble keeping them in stock due to popularity.
Me thinks a perfect logo giveaway item for radio - especially AAA, AC or any station with strong female demos.
