redbox offers a free1-night movie rental when you text "RBAPP" to 727272. (You'll receive a unique coupon code almost immediately.) That's the first redbox DVD freebie we've seen since March. Note that although the code is valid on Blu-ray rentals, the code only discounts your purchase by $1.20; Blu-ray rentals start at $1.50. The coupon must be redeemed online at redbox.com, it cannot be entered directly at the kiosk. Other exclusions may apply. Search for a redbox kiosk location near you. Code expires September 30.
