Consumers spent $839.02 billion online in the U.S. in 2020, up an incredible 40.3% jump compared with 2019. That’s the highest annual U.S. ecommerce growth in at least two decades. Total retail sales, including merchandise purchased in stores and through catalog/call centers, increased 5.7% last year to nearly $4.00 trillion, early analysis from Digital Commerce 360 shows. This is the highest growth in total retail sales since 2005. This means ecommerce now accounts for 21.0% of total retail sales, up from 15.8% in 2019 and 14.3% in 2018.
