When you think of website retail, the first name that probably comes to mind is Amazon.com, Inc. (NASDAQ: AMZN) — and with good reason. According to Deloitte’s 2017 Global Powers of Retailing Report, the e-commerce giant is the largest e-retailer in the world. Another company that likely comes to mind is discount leader Wal-Mart Stores, Inc. (NYSE: WMT), which takes the spot as top retailer and sits 4th in e-commerce as it battles to expand its online sales in a market dominated by Amazon.
