Amazon reportedly plans to open department stores

Company's latest move comes after years of competing against brick-and-mortar retailers

Amazon is planning to open department stores after years of competing against, and in some cases helping to destroy, the very same traditional brick-and-mortar retailers.

The company's latest move to bricks and mortar, first reported by the Wall Street Journal, comes after Amazon earlier this week eclipsed even Walmart in overall sales to become the world's largest retail seller outside China.
