Carl’s Jr. is boxing out rival Jack in the Box with a promotion that rewards customers for driving past it and choosing a different burger stop.
Through June 30, Carl’s Jr. is offering a free Sourdough Star sandwich to members of its rewards program who submit proof that they passed a Jack in the Box location without stopping. The sandwich, which recently returned to Carl’s Jr. menus, features a charbroiled beef patty, cherrywood bacon, grilled onions, American cheese, lettuce, tomato and mayonnaise.
