This just in- 20% off at all participating Jack in the Box restaurants. I had the urge for a Pumpkin Pie Shake the other night at the San Diego-Murphy Canyon location and saw the sign at the drive through. Just show them your military ID card!
Feel free to post which locations are/are not participating in the Comments section!
