Just from a different perspective, for us it's the trading experience, esp. the experience for our kids. We're orlando locals, so we kind of stumbled on pin buying many years back when the outlets were selling 99 cent pins, but we soon realized how much fun the kids have interacting with cast members when they trade. It creates some really special moments for them (esp. on the cruise ships) and some great memories of were they were when they traded and with whom they traded.
