Smashburger is serving up a massive BOGO deal! Score a free burger or "Big Dog" when you buy one through March 22. Here is the secret to finding the offer.

You know what is better than a juicy burger? Two juicy burgers! Right now, Smashburger is making our fast food dreams come true with a fantastic buy one, get one free deal running through March 22. You can grab a buddy (or just bring your appetite) and score a free burger when you purchase one. If you are not in the mood for a burger, you can choose their famous Big Dog instead. If you have never had one, a Big Dog is a massive quarter-pound All-Angus beef hot dog that is split open and griddled to crispy perfection. It is a massive win for your tastebuds and your wallet. If you are craving even more double deals right now, be sure to check out our Shake Shack BOGO freebie to keep the burger party going!

To grab this tasty offer, you just need to be a part of the SmashRewards program. Once you are signed in, simply check your MyRewards account for the BOGO coupon. The best part is that joining their loyalty club keeps the savings rolling in long after you finish your meal. You will earn 10 points for every dollar you spend to use toward future free food. New members even score a sweet five dollar discount on their first order over fifteen dollars. It is truly one of our favorite March food deals happening this month.
