The US retailer is using the social location game, SCVNGR to drive sales in their footwear and fitness departments. Using a specially developed version of the game, they are encouraging their customers to check-in and try on items at various locations in their stores. Users can also upload photos. In return Sears are offering ‘players’ discounts of up to 20% on purchases and loyalty points. The app certainly ticks a lot of the boxes on getting customer engagement through mobile. It will be interesting to see how this initiative works out.
