Aghast at the hulking, shapeless being that lurched toward the registers, cashiers at the local Green Valley Parkways Walgreens confirmed Thursday that the soulless mass shambling down the aisle was nothing but a lumbering golem of rewards cards. Do you have a Balance Rewards card with us, sir? said cashier Matt Hershlag, 25, before scanning one of the loosely hanging cards that formed the body of the immense supernatural creature who, sources confirmed, was more plastic and barcodes than man. Thanks. Thatll be $8.49. At press time, the towering anthropomorphic heap of loyalty cards had paused to search his Sprite bottle purchase for a My Coke Rewards product code in hopes of winning a free six-pack.
