You can get a free movie rental from redbox just by giving them your e-mail address (click on “Get a Free Rental” text near top). This offer is only good if your e-mail address is not already in their system. I’ll be getting my free movie tomorrow when I do my grocery shopping.
Here’s what Redbox says about this offer and the use of your e-mail address: “Get a free rental (good at redbox only, not online) AND redbox’ snappy and snazzy weekly email with new releases, occasional rental offers and special deals. You can’t go wrong. And, of course, redbox will share your email address with no one. That’s a promise.”
