How to Claim: The Cheat Sheet
- The Deal: Buy One, Get One FREE Mix 'n Match K-Shack Items.
- Dates: April 9th to April 22nd, 2026.
- Where to order: Shake Shack app, shakeshack.com, or in-store kiosks.
- Promo Code: SPICYSWEET
Pro Tips: The Fine Print
- The "Lesser Value" Rule: The free item will always be the one with the lower price tag in your cart.
- Skip the Drive-Thru: This code is a "digital only" vibe. It won't work at the drive-thru or on third-party apps like DoorDash or Uber Eats.
- Kiosk Win: If you are already at the Shack, you can still use the code! Just head to the in-store kiosk instead of the register.
- Max Savings: Since the value caps at $17.79, you can basically get their priciest K-Shack burger for free if you buy another one of equal or greater value.
