During the 2013 holiday season, US stores got half the foot traffic they did three years ago, says The Wall Street Journal. Instead, we’re shopping online and shifting our attention towards new watering holes — apps like Instagram, Pinterest, and Wanelo — places to show off our new designer jeans and designer vacations. It is estimated that by the end of 2014, nearly a third of all online shopping will be done on mobile devices. Brands are creating their own apps, but you’re not going to download 50 different apps to go shopping, says David Tisch, co-founder of Spring, which launches today on iPhone.
