Shake Shack has a promotion that will get you a free shake when you make a purchase of at least $5. Add a shake to your Shack App order + use code “LYFT2SHACK” at checkout. On top of that, you can also get a 20% off your ride to and from any Shake Shack in NYC. Use the same code “LYFT2SHACK” in the Lyft app under “Promos.”
