I've never heard of Redbox before, but after using their store locator, I found out I have a million rental locations around me. So I'm gonna use code W6CT98 and pick me up a free DVD rental.
This code expires tonight at midnight, so pick up a movie on your way home from work. And don't let me hear any excuses about “working late” or “rushing home to feed the kids.” Just do what I do with my siblings: give them a few of those decorative wax fruits to gnaw on for a while and they'll be good as new. Sure, doctors might tell you that children need more sustenance than that, but who are you going to listen to? Licensed professionals or a guy who read WebMD once and used to watch ER?
EDIT: Turns out Redbox routinely offers free DVD codes and here's a site that tries to keep track of them all. Might be a good site to bookmark if you use Redbox often.
