Here is this weekends Free RedBox code to get a movie for the weekend. Now I am not sure about the rental return policy if you get the rental on Saturday and the location you got it from is closed on Easter Sunday. So be careful about returning it in one day so it is totally free.
Enter the code MISSYOU in the promotion screen to get your free rental. You will still have to swipe your credit card in case you keep it longer than one day. You can also return it to any RedBox location. Enjoy your movie!
