Ohhhh… I like this coupon because I enjoy Grandma Cookies! 20% off Frito-Lay and Grandma Cookies coupon can be combined with your Subscribe and Save order. Last time this coupon was around, I picked up the Grandma’s Chocolate Brownie Cookies – they are sooo YUMMY! There are several flavors of cookies to choose from and chips as well! What is your favorite chip or cookie to pick up with the 20% off Frito-Lay and Grandma Cookies coupon?
