For its members only, Sam's Club offers the Frito-Lay Classic Mix Variety Pack 50-Pack for $9.78. Better yet, opt for in-store pickup to drop it to $9.28. That's tied with our March mention and the lowest price we could find by $3. It includes 16 bags of Cheetos, 12 bags of Lay's Classic Potato Chips, 10 bags of Fritos Corn Chips, eight bags of Doritos Nacho Cheese Tortilla Chips, and four bags of Lay's Sour Cream & Onion Potato Chips.
