If shoppers are looking for something out of the ordinary this holiday season, Macy’s is hoping they’ll hunt for it at one of its pop-up marketplaces. The department store chain is beefing up this offering while adding new experiences, such as virtual reality headsets, to make shopping easier and, it hopes, to drive sales. In a unique move, Macy’s will partner with Facebook to add about 150 brands that currently advertise on the social media platform to sell in its shops.
