I remember me and my cousins used to run up and down the aisles, pulling off those coupons that come out of those little machines. We liked to see who'd get the most.
Hey! Me and my cousins did that too! Then we'd try to ride bikes into the store and sit on the Coke displays, I would always stick my head between the produce and the top of the case because there are mirrors up there, and open all the freezer cases in a row.
Oh, and our local Piggly Wiggly, they had this theatre inside that always played Star Wars, with huge cardboard cutouts of C3PO and R2D2. If you bought a Disney book you got a free drink or Icee.
My grandma always shopped at Food Lion, because they take those food stamps or whatever, and I loved that one commercial where the people chopped the vegetables in mid-air. She always bought me Canada Dry, Nestle Quik, and Flintstones push-up pops.
