Redbox offers a unique coupon good for a free 1-night DVD rental, free Blu-ray rental, or 50-cent video game rental when you text "movie time" to "727272". That's the best coupon we've seen from Redbox since August, beating yesterday's expired mention of a free DVD rental, 30-cent Blu-ray rental, or 80-cent video game rental. (It's also the best price we've seen this year for a video game rental.) Your unique coupon code must be redeemed within one week.
