Monday, December 13 marks the beginning of Jack In The Box’s holiday celebration, the 12 Days of Jack. This money-saving event is offered exclusively though the Jack app, where a series of in-app, one-day-only deals will be posted between December 13 and 24.
As an incentive for customers to download the Jack app and take part in the 12 Days of Jack, Jack In The Box will also give you 20% off your first in-app order after you newly download the Jack app.
