Amazon.com Inc. plans to open several large physical retail locations in the U.S. that will operate akin to department stores, a step to help the tech company extend its reach in sales of clothing, household items, electronics and other areas, the Wall Street Journal reported. The plan to launch large stores will mark a new expansion for the online-shopping pioneer into bricks-and-mortar retail, an area Amazon has long disrupted. Some of the first Amazon department stores are expected to be located in Ohio and California, the people said. The new retail spaces will be around 30,000 square feet, smaller than most department stores, which typically occupy about 100,000 square feet, and will offer items from top consumer brands. The Amazon stores will dwarf many of the company’s other physical retail spaces and will have a footprint similar to scaled-down formats that Bloomingdale’s Inc., Nordstrom Inc. and other department-store chains have begun opening, the people said. It is unclear what brands Amazon will offer in the stores, although the company’s private-label goods are expected to feature prominently. Amazon sells scores of products including clothes, furniture, batteries and electronic devices through many of its own labels. The plans aren’t yet final and could change, according to sources.
