A 4.5% cut in average price has helped keep McCain in growth. The brand ran ads celebrating the 35th anniversary of the oven chip, although most growth came from another product, says the brand: Ready Baked Jackets. “Jackets show that with the right product, consumers are willing to change their cooking habits,” says marketing director Mark Hodge. In November, McCain teamed up with Cathedral City to promote jacket spuds and cheese as the ultimate winter meal.
