Instagram took its next step to becoming a full-fledged commerce business today, announcing that it is bringing a checkout feature to its mobile apps. With checkout, you can store your payment information with Instagram to make purchases more quickly. In return, Instagram is charging retailers a selling fee. More than 20 brands will use checkout to start, including Nike, Adidas, Dior, H&M, MAC Cosmetics, Michael Kors, Oscar de la Renta, Prada, Uniqlo, Warby Parker, and Zara.
