Don't discard your candy wrappers

Across the UK, six chocolate bars will have a GPS chip hidden inside the wrapper; when the wrapper is taken off the bar, it will activate the chip, so that Nestlé can track down the winner within 24 hours and hand them a cheque for £10,000. The chips will be hidden in the wrappers of KitKat 4 Finger, KitKat Chunky, Aero Peppermint Medium and Yorkie Milk chocolate bars.
