Elizabeth has been spending time reading, gathering, and organizing coupons. Shopping is now an experience to calculate the best deal possible - rather than just food shopping. She now carries a bag with coupons and scissors (to cut out coupons). She does not record all prices - only for items she thought was a good deal. My best percentage is 67% off cereal. Elizabeth has done as well as 84%. She's also earned 20 cents off each gallon of gasoline. What is your best discounted purchase?
