It’s almost that time of year again, the magical season of the Pumpkin Spice Latte that brings fanatics to Starbucks in droves. To amp up the excitement, the coffee giant is using Facebook to host a social marketing contest. The challenge and its companion app will be revealed on the Starbucks Facebook Page on Monday, reports Mashable. The contest will pit cities against each other, and the winning city gets the Pumpkin Spice Latte a week before its official release date.
