There are deals aplenty on National Cheeseburger Day, but are you ready to pay $10 for a burger otherwise?

If you’re a burger eater, you’ll have plenty of reason to celebrate on Sept. 18. It’s National Cheeseburger Day, after all, and many fast-food and fast-casual chains will be offering deals to mark the occasion. McDonald’s MCD is even selling double cheeseburgers for a mere 50 cents.
