In order to unlock the coupon (go here), you’ll either have to provide Jack in the Box with your email address or a mobile phone number. By doing so, you’re basically agreeing to receive messages from Jack in the Box related to new products, coupons and deals. You can opt out at any time.
Jack in the Box’s current lineup of Buttery Jack burgers includes the new Triple Bacon Buttery Jack, Bacon & Swiss Buttery Jack, and the Classic Buttery Jack.
I obtained my coupon via the method above and it has an expiry date of February 14, 2017.
