There's a new promo code ACME26 to get a free one-night movie rental with at your local Redbox. You can only use one code per transaction, so if you want to use more than one code just make two transactions.
You need to make sure you return your one-night movie rental before it's due to avoid any late charges. And Amy at MomAdvice says you can use each promo code more than once if you use it with a different credit card. Check to find your closest Redbox location, there are over 17,000. These codes can only be used "at-the-Redbox" and can't be used online to reserve the movie you want.
Other codes that are probably still valid:
DVDATWAG (works only at Walgreens locations)
Monday Freebie First Monday of Month
Plus the first Monday of each month a code is released that's valid for a free movie that Monday only. You can sign-up for text messages here to get a unique code for your free movie that can only be used once. I'll share any codes that I find that are shareable, but that code they send out via text message is not shareable.
Thanks, Freebies for Mom!
