Jack in the Box's (JACK) Menu In May Jack in the Box raised its menu prices by 1.5%. The fast-food chain said it was raising prices cautiously because it was aware of the highly competitive environment in terms of consumers' food choices. It said any future menu prices would be modest. Jack in the Box raised prices as overall commodity costs rose 5% in its recent quarter. The chain paid more for everything including beef, produce, cheese, pork, dairy and shortening. Overall commodity costs are expected to grow as much as 5.5% in 2011, so future menu price increases are certainly not out of the question.
