Chipotle has had a rough year so far, but it's turning things around. The E. coli outbreak is over, and after all locations closed for part of the day on Feb. 8, Chipotle is doing something amazing to win customers over: giving away free burritos! All you have to do is text "raincheck" to 888-222, and you'll get a text with a link to follow. After you enter your name and zip code, you'll get another text with your coupon within a few days. Chipotle clearly knows the way to its customers' hearts.
