South Florida Savings Guy Recommendation
Several of these National Cheeseburger Day offers require a free restaurant rewards account or mobile app. If you’re planning to take advantage of a deal, consider downloading the applicable app and creating your account before September 18 rather than waiting until you’re at the restaurant.
For South Florida diners, individual restaurant participation can vary. Check the offer inside the restaurant’s app or website and confirm your nearest participating location before heading out.
South Florida Savings Guy will continue checking for additional verified National Cheeseburger Day deals as September 18 approaches. Check back for updates.
