You ever have so much Halloween candy you don’t know what to do with it? Yeah, me neither. For those suffering with such excessive candy problems, however, there is a solution: Halloween Candy Buy Back. Since 2005, this campaign, Operatio Gratitude, supported largely by dentists, has purchased Halloween candy at $1/pound and shipped it to U.S. troops overseas. They have a handy search engine where you can type in your zip code and find the closest drop off location.
