Sweedish Department store, Åhléns, has redefined the meaning of "act fast" to take advantage of an amazing discount. They displayed a series of really fast moving Instagram videos featuring a variety of items they sell, from beauty products to furniture, and challenged people to take a good screenshot of any item they wanted. If they did it successfully (and posted it to their Instgram account), they got 50% off that item at checkout. Now how's that for tying sales to social media ya ROI fiends?!
