Marks & Spencer Launches New Clothes Swap Program

U.K.-based Marks & Spencer has launched Shwopping, a new initiative that the retailer claims will revolutionize clothes shopping and help consumers to live more sustainable lifestyles. Marks & Spencer wants to put used clothing to good use. Instead of throwing it out, the retailer is asking customers to "shwop" it — give an unwanted piece of clothing every time they buy a new one.
