If you have a couple older video games lying around that you wouldn't mind getting rid of, Future Shop and Best Buy are running a trade in event you might be interested in. For a short while, you can trade in any two select video games and get $60 worth of store credit. The lists can be found below and they include games for all consoles including handhelds. Though the list is primarily comprised of newer titles, there are some older ones that make it worth a look.
Trade in events aren't anything new but this is the first we can recall where you can swap games for store credit, or at least this much store credit.
The promotion is live now and thanks to nguyentri for pointing this one out.
