The warehouse sector has experienced growth since 2012 as more consumers buy goods online and return them to eCommerce retailers. 8% of goods purchased in physical stores are destined to be returned, but online shoppers typically return 30% of their purchases. Online retailers are dealing with "reverse logistics," otherwise known as customer returns, by renting out 700 million square feet of warehouse space nationally according to firms in the industry. Another company that assists etailers with customer returns said that consumers will return $100 billion in holiday gifts. Returns take up more space and require more labor than selling products as they have to be sifted through by hand. "The demand for the space is only going to increase in warehouses unless and until we find a better solution to either return to the store or better incentives for consumers not to return the goods," said Spencer Levy, CBRE's chairman of Americas research and senior economic advisor. "We're talking tens of billions of dollars of goods that have returned and need to either be returned to market, or very often destroyed if the value is no longer there."
