Use coupon code PLKMP982 to get a free Redbox DVD rental! This is available through 4/30 and ONLINE or through APP only (not at the box!), but I suspect that they will kill it before then. Don’t wait too long to use yours!
You should be able to use this code five times per credit card with separate transactions. I have always been most successful when reserving online and picking up my order at the box. Enjoy!
