• At Papa John's Pizza, order any large pizza at regular price and get a second large pizza of equal or lesser value for free via coupon code "BOGO327".

• Old Navy printable coupon: 30% off entire purchase Old Navy cuts 30% off your entire in-store purchase via this printable coupon. To get this coupon: Click here to start, then select Start Hunting. Match (drag and drop) Kelly's head to mannequin "A", Amy's to "B", and Heather's to "C"
  the resulting "get coupon" tab yields 20% off of two items, but don't click it
  instead, wait approximately one minute until a dolphin appears in the water behind "Amy", then click on the dolphin while it's in the air to receive a 30% coupon. That's a very annoying way to get a good deal, but a girl's gotta do what a girl's gotta do!!
