Where to Score Cheap Burgers for National Cheeseburger Day

No one really needs a reason to eat a good cheeseburger, but if there's any good excuse, it's National Cheeseburger Day on Sept. 18. Many fast-food and restaurant chains are offering cheap — or even free — burger deals, so you could theoretically celebrate the day with multiple meat-and-cheese-filled meals from these spots. Just don't tell your cardiologist.
