Buy One Shake Shack and Get One Free This Summer

Milkshakes are best drunk in pairs, especially in summer. And right now, New York burger chain Shake Shack is offering to buy one milkshake and get one free deal until July 31st at participating locations. Share with a friend or take both for yourself.

To get your pair of shakes, you need to place an order through the Shake Shack website or app , and you must be logged into a registered account for the deal to work. Add two cocktails of any size to your basket, choosing any flavor, including tiramisu, dream book (vanilla and blood orange), non-dairy chocolate, and their hand-spun cocktails made with frozen custard. Any of their “Limited Time Shakes” are also included in the deal.

You need to schedule your order between 14:00 and 17:00 local time; use promo code “SHAKEITUP” at checkout and the cheaper of the two milkshakes will be free. Any additives such as whipped cream or malt will be charged extra.

Keep in mind that you can’t request an in-store deal, and shipping or pickup isn’t available. And finally, you are limited to one offer per order, but you can order (almost) all summer, until July 31st. You can read all terms and conditions here .

Not all Shake Shacks are included in the deal, and not all Shake Shacks at airports, stadiums, visitor centers, museums, or baseball stadiums. You can find all Shake Shake locations here .
