Did you know you can still rent video games? It's true. And between now and August 13, you can get a free one-night rental on select PS4 and Xbox One games. All you have to do is reserve the game you want online (the discount is added in your cart), go pick it up, and you're looking at a night of free gaming.

Redbox will hold the game at the kiosk you select until 9 PM local time the day after you place your reservation. You can keep the game longer, but naturally you'll have to pay the $3 rental fee for any additional nights.
