Amazon has select Frito Lay Variety Packs listed below on sale when you ‘clip’ the corresponding coupon on the product page and checkout via Subscribe & Save. Shipping is free.
Note, must be logged in to clip coupons; coupons are typically limited to one per account. You may cancel Subscribe & Save anytime after your order ships. Select the later date from the “First Delivery On” menu to get traditional S&S checkout instead of adding to your cart.
