Today only, October 9th, it looks like you can enjoy a FREE rental at any Redbox Kiosk when you use coupon code XD33WQAP at checkout.
You will want to note that this is an unadvertised coupon code. So this coupon code may not work for everyone. Definitely worth a try though if you want to do a movie night tonight.
**Coupon code only valid for one free night. Any additional nights will be charged at the regular rate. Code not valid on Blu-ray or Video Games.
