The overwhelming majority of plastic gift cards sold (some 75 million pounds a year) can easily be recycled through a free program called Swipe It. Swipe It lets you collect and send in all of your old and used cards to be recycled into new plastic products. All you have to do is visit swipeit.com, enter the number of gift cards you want to recycle and mail them in. One other idea is to invest in gift cards that can be recharged and reused by the retailer. When the balance is up, you can reload it and give the gift card to someone else as a present.
