This time last year a little clothing store located in South Africa was running an outstandingly creative customer engagement social media campaign. Urban Degree gave store customers an $8 in-store credit if they would try on clothing from the retailer and take a selfie, share the image online, and include the hashtag #UrbanSelfie
There's a lot of opportunity for other industries to do this. Why can't restaurants provide a $1 discount for guests who take and share a photo of their food? When you provide small incentives for your customers to promote your products and services, they will.
