Free Shake from Shake Shack with $2 Donation Through September 8, 2019

The 8th Annual Great American Shake Sale is happening at Shake Shack from now through September 8, 2019. During the promotion, you can donate $2 to No Kid Hungry (a non-profit aimed at ending child hunger in the US) at your local Shake Shack and get a promo code good for a free shake that you can use via their app or online.

The charity fundraiser is available at most US locations and the free shake code is good through September 30, 2019 at participating locations. While you have to donate the $2 in person, you cannot use the code at the cash register or kiosk (it's in-app or online only).

The shake at Shake Shack normally goes for about $5.99.
