But Wait, There's More
It wouldn't be National Burger Month if the fun stopped there, now would it? Alongside free burgers every week this month, Shake Shack is also running a sweepstakes to crank up the excitement and give a little extra back to fans. By entering here before June 1, participants will have the chance to become one of two winners who receive free burgers for an entire year.
Terms and conditions, of course, apply. As for the weekly free burger promotion, customers are limited to one free burger per order, so lunches this month are about to get a whole lot more filling. Bring your friends, plan a date, make an afternoon out of it and enjoy a few extra bucks in your pocket while you're there.
