Here's today's free movie! Find your local Redbox, choose your movie, and enter the code! For my local readers, there's now a Redbox in the Henry St. Meijer as well as both WalMart locations. I don't know about other Meijer stores though, check that locations link above to find out for sure.
Today's free code is 4CW33N
The code is good until midnight. You will need to put in your credit card info, but you will not be charged as long as it is returned by 9pm the following evening (if it's late they charge $1/day). You can use the code more than once if you use separate credit cards.
