Set your alarm! Tomorrow is National Avocado Day, and Chipotle is pulling out all the stops to bring fans in. If you order your meal via Chipotle's app or site, you'll score a free serving of guacamole. Meaning for 24 hours, guac will be free! You can redeem it with the code "AVOCADO" when you check out. It can come as part of your main, like in a burrito or on top of a bowl, on the side, or with some chips. In the past when Chipotle's given away free guac, they've made fans play games.
