Right now you can get a $1/1 Sunchips or Ruffles Printable Coupon. This coupon prints with the Walgreens logo on it but it is a manufacturer coupon that could be used at any store that acepts manufacturer coupon. You could probably use this Sunchips or Ruffles Printable Coupon to get a bag for around $1.50 after coupon. I often see these on sale 2/$5.
Thanks Coupon Pro!
