Early analysis from Internet Retailer show online retail sales in the U.S. crossed $517 billion in 2018, a 15.0% jump compared with 2017. The growth in retail sales in physical stores reached 3.7% last year. This means that ecommerce now accounts for 14.3% of total retail sales when factoring out the sale of items not normally purchased online, such as fuel, automobiles and sales in restaurants. And it also means that in only a decade, the web has more than doubled its share of retail sales. Ten short years ago, ecommerce was at 5.1% of total retail purchases.
