There’s no better price than the price of free. There’s also no such thing as a truly free lunch. But Shake Shack currently is running a promo that’s the next best thing — A code for a free burger if you download their app for mobile ordering.

Get App-y! Download the #ShackApp & create an account before 2/28 to use the code "shackappy" for a burger on us: https://t.co/FvJ60b7ToK pic.twitter.com/9YkTnFMR3r

Free burgers = bliss.
