Today (June 6), Sonic is offering half-priced cheeseburgers. What’s the occasion? I guess just because since National Cheeseburger Day is on September 18.
The offer is available for only single-patty cheeseburgers. Add-ons cost extra. Cannot be combined with other offers. Glory lasts forever.
There is no limit on the number of cheeseburgers you can buy at the discounted price. But it’s only available at participating Sonic locations, while supplies last.
