The deal is only good on single-patty cheeseburgers and this time around, there's a limit of five per order. It's good at participating Sonic locations nationwide and you'll need to mention the deal when ordering.
A Sonic Cheeseburger typically costs around $3.29 (may vary) and includes American cheese, crinkle-cut pickles, chopped onions, shredded lettuce, sliced tomatoes, a seasoned beef patty, and a choice of either mayo, mustard, or ketchup.
