Here is the Monday promo code that will let you rent a movie free tonight at RedBox - those red kiosks inside grocery stores, restaurants, and pharmacies.
When you select the movie you want to rent, click on the Promo Code button and enter: 57DRW3 through midnight tonight, Monday 11/17. Your cost will drop from $1.00 to $0.00, though you'll still have to swipe your credit card in case you decide to keep the movie longer than one day, and you'll be charged for subsequent days.
But if you return it before 7:00 pm Tuesday night (9:00 pm at some machines), you will not be charged a cent.
