Showrooming has become a major challenge to brick-and-mortar retailers, but Snapchat could provide some unexpected solutions. The ephemeral nature of the app allows businesses to play with fun promotions like in-store only coupons for unknown amounts and scavenger hunts. Brands can also build anticipation by sending snaps of upcoming arrivals and events, or encourage customers to send snaps of products (and the brand profile on the app) to friends in return for a coupon. Retailers willing to experiment with the platform could be rewarded. (AdvertisingAge)
