I saw someone at Smith's loading up their cart with Lay's chips, so I had to go speck it out. Now I know why! There are peelie coupons for $1/2 Family Size Lay's bags (seen at my store in Brigham.) Pair that with a store promotion to pick up each bag for only $1.27 each!! This is a scenario I suggest:
Buy 6 Lay's Family Size Chip Bags, $1.77 (must buy 3+ to get the $1.77 price)
Buy 3, Get them for $1.77 Promotion
And Use (3) $1/2 Family Size Lay's Potato Chips Peelies found on product
Final Price: $1.27 each!
