Redbox: Rent 2 Movies, Get 1 Free (Summer Promo!)
Redbox is kicking off a new “Summer Fun & Games” promotion. Through June 12th, rent 2 movies at the same time from Redbox and you’ll receive a code valid for a FREE one-night DVD rental! Just be sure to enter your email address at checkout (or whenever you reserve online) and you’ll be emailed a promo code good for a free one-night DVD rental within 72 hours! Head on over here for more details.
I dont think they send the promo if you reserve online only if you go to the redbox and get them.
I just checked the Redbox site and it says you can reserve online. It takes up to 72 hrs to get your promo code.
