Here's something in the trash that's worth cash: wine corks. Craft enthusiasts have gone mad for turning wine corks into decorative items. There's even a growing market for old wine corks on resell sites like eBay. Selling for about 10 cents a cork, if you have saved an impressive collection, you can sell them online and make some serious change. You can also recycle your corks; visit recork.org to find a collection box near you.
