TerraCycle is a recycling and upcycling company that collects traditionally non-recyclable waste and uses it to make new, affordable products.  Through a partnership with Old Navy, you can do the right thing for the environment and send your old flip flops to TerraCycle FREE of charge through the Flip Flop Brigade. For every 25 pairs sent in using a prepaid shipping label, you will receive a coupon for a FREE pair of flip flops from Old Navy and a packet of coupons for $10 off a purchase of $40 to use yourself and share with friends and family!  By doing something good for the planet, you can do something good for your wallet as well!
