We all have movies and music in our entertainment library that we were sure to watch or listen to more than once, right? Then, reality sets in and you never push play again. (Again, why did I buy Michael Bolton’s Greatest Hits?) Well, the recently opened Tradesmart in Littleton gives you an opportunity to sell your ”previously-used”, space-taking, never-played-again CDs, DVDs and video games. You can earn cash back or, better yet, more if you take store credit. If you’re not selling, you can find lots of great deals on used and new merchandise. Be sure to check their weekly in-store ad for specials and coupons. Right now, there’s only one location in Littleton with the hopes of more stores opening in the future. 8500 W. Crestline Ave., Littleton, 303-904-2672.
