Free fries at Jack in the Box
The new fries are supposed to be crispier and more in the style of rival McDonald's. Guess the thick cut "natural" fries were not selling too well. Curly fries are still on the menu and the prices will remain the same, according to Fast Food Maven.
Watch the Jack in the Box commercial about the new fries if you want. It's kind of lame.
