Who doesn't love free guac!
According to Bustle, they’re offering a limited-time deal for free guac with a purchase of an entree and it’s super easy to get. The whole point is to have people join the Chipotle Rewards Program during the "Guac mode" coupon.
Once you sign up for the program, it automatically puts the rewards in the app. For the ones who already have the app, it should be in the app for you to use.
Not only do you get free guac, but they're also offering reward members free delivery on two days during February on $10 or more Sunday Feb. 16 or the 23rd. Offer is only available until Feb 20th.
