The homelessness charity, Shelter Scotland, has teamed up with location-based service, Foursquare, to literally put its charity shops on the map.

Not only will checking in to any of the charity’s eight shops in Edinburgh gain you a specially designed Foursquare badge, but collecting them all enters you into a prize draw to win the prints of the designs. Not only that, but users of Foursquare will get discounts on the items they buy from the stores.

A start of a new trend, perhaps? Read some more from Shelter Scotland’s website.
