Here’s how to get a free cheeseburger from Shake Shack delivered to your door today

We hope you’re hungry, because we have great news for Shake Shack lovers in 17 cities across the U.S. You can get free Shake Shack cheeseburgers from Postmates delivered to your door TODAY, Sunday, December 17th. Yes, you read that correctly: free Shake Shake cheeseburgers, plural. According to Thrillist, Postmates, one of our favorite delivery apps, teamed up with the burger franchise and will not only let you get a free cheeseburger, but they’ll also deliver one to one of your friends. Also for free. Yup, it looks like Christmas came early, and our appetites are so grateful.

We can never get enough Shake Shack — even the vegetarians among us! — so we love when deals like this happen. And this isn’t the first time Shake Shack has treated us to free burgers. Back in September, they partnered with DoorDash and gave away free cheeseburgers for National Cheeseburger Day. And in January, Shake Shack gave away free burgers to those who downloaded their Shake App. But today’s promotion is extra special, because you get to share the cheeseburger love with a friend. Just think how happy your BFF will be when their doorbell rings and there’s Shake Shackat the door. Yum.

There are two catches to the deal.

One, you must live in one of the 17 participating cities. And two, you have to be an existing Postmates user, then refer a friend to the app. So you’ll use a promo code to send a free cheeseburger to your friend, then you’ll receive a $10 credit for your own cheeseburger. The deal’s actually been happening all week, and today is the last day to cash in on your free Shake Shack cheeseburger dreams, so don’t miss it.

Free Shake Shack for everybody!

Another deal from the burger connoisseurs that ends today is FREE delivery. So if you want to skip the give-a-burger-earn-a-burger deal, but are still craving something else (perhaps fries or a hot dog?), Postmates will give you free Shake Shack delivery today.

The 17 participating cities are Atlanta, Austin, Baltimore, Boston, Brooklyn, Chicago, Dallas, Houston, Los Angeles, Las Vegas, Miami, New York City, Orlando, Philadelphia, Phoenix, San Antonio, and Washington, D.C. We don’t know about you, but our mouths are definitely watering thinking about this deal.

One for you, one for a friend!

Hold our calls and cancel our plans. There’s free Shake Shake waiting to be devoured.
