For the rest of 2012, when you buy a $30+ in Chipotle gift cards, you can receive a free burrito, bowl, order of tacos, or salad. Just present your receipt acknowledging your purchase on or before December 31st. Though the offer ends on December 31, 2012, but the freebie can be redeemed through January 31, 2013. Tips: You can load up with extra meat and guacamole and won’t be charged extra because it’s free! Also, be sure to split your gift card purchase transactions so you maximize your freebies.
