What's the only thing better than grabbing a Mcdonalds burger for lunch? Not having to pay for it! Lucky for Canadians, today you can nab yourself an iconic cheeseburger for free, thanks to Mcdonald's latest promotion. While the burger is free, there is a small catch attached to the offer. You've got to order something via Mcdonald's smartphone app in order to get the coupon that gets you your free burger. Though, if you just grab your fries on the app, then the burger you pair with it won't cost you a dime, so it's still a great deal! Via Mcdonalds Canada If you're wondering why today of all days, it's actually because September 18th is National Cheeseburger Day so there really is no better day to eat a cheeseburger if you ask us! Though today isn't the only day you can grab deals, Mcdonalds has been doing promotions all month connected to their app. Meaning that if you miss out on today, there still is the chance to grab something else from the iconic fast food chain for free in the near future- so keep your eyes peeled! There’s only one thing better than lasers and cat sweaters and it’s FREE cheeseburgers. 🍔 Get one with any purchase with the My McD’s app tomorrow!

Good luck and happy National Cheeseburger Day!
