Here's a great deal for anyone who wants to try out a game for free. Between now and May 21, Redbox is offering a free one-day rental of any PS4 or Xbox One game you can find in stock. All you have to do is select the game you want right here and choose where you want to pick it up. Thanks to an automatic coupon, the one-day rental becomes free in your cart.

You have to pick up the game by 9 PM (local time) the day you reserve it. And if you don't return it by 9 PM the following evening, you'll be charged $3 for an extra day--and $3 for every day after that. Even so, this is a great deal if you want to play a game for a day, or try a game you think you might want to buy.
