Before you sign up

  • Not valid at a drive-thru, and not through third-party delivery apps. It has to be a kiosk, Shake Shack's own app, or its own site.
  • The $10 minimum excludes the Chicken Shack itself, gift cards, taxes and delivery fees — so a $10 order with the sandwich counted in it does not reach the threshold.
  • It excludes the Avocado Bacon Chicken and Chicken Bites, and paid add-ons such as avocado and bacon are not covered.
  • It cannot be combined with any other Shake Shack offer or promotion.

Where a shop’s terms turn on visa status, the deal says so — checked against the shop’s own terms, and including the offers that turn out to be closed to people on a visa. That is the part nobody else prints.

What people found

Nobody has said anything yet. If you used this, whether it worked is the most useful thing you can add.

Sign in to add what you found. One tap, no password to invent — and it brings you straight back here.

The deal itself is a public promotion, and the member who found it earns nothing from posting it. A row in the stack marked as a referral does pay the member whose offer it is, at no extra cost to you, and says so on the row. HelloStamped takes nothing either way.
