U.S. retailers grew their online sales by 16 percent in 2014, while total domestic store sales grew just 2.4 percent. U.S. online merchants grew their sales to more than $256 billion.
Online sales outpaced overall store sales, which reached about $3 trillion, by more than six times, according to Internet Retailer's 2015 Top 500 Guide. Of all retailers ranked in the Top 500, online sales were up 15.7 percent to about $297 billion.
The top-ranked retailer for Web sales in 2014 was once again Amazon (NASDAQ:AMZN), with with an approximately 19.5 percent increase in sales totaling $88.98 billion. Overall, Amazon accounted for 31 percent of all U.S. Top 500 sales and 26.1 percent of all U.S. e-commerce sales in general.
On the Top 100 list, Staples (NYSE:SPLS) ranked No. 4 and Office Depot (NASDAQ:ODP) ranked No. 6. However, once their $6.3 billion merger, which was announced in February, gets finalized, the retailer's combined operations would result in total annual Web sales of $15.53 billion, and total annual sales of $34.35 billion. Those numbers would make Staples the biggest office supply retailer, both on and offline, positioning it ahead of Walmart (NYSE:WMT) as the No. 3 online retailer in the Top 500.
