Online retailers are seeing Black Friday-like sales due to the impact of the COVID-19 pandemic on their business. According to new data from Adobe’s Digital Economy Index, U.S. e-commerce jumped 49% in April, compared to the baseline period in early March before shelter-in-place restrictions went into effect. Online grocery helped drive the increase in sales, with a 110% boost in daily sales between March and April. Meanwhile, electronic sales were up 58% and book sales have doubled.

The data comes from Adobe’s index of the digital economy, which analyzes more than one trillion online transactions across 100 million different SKUs. The company works with 80 of the top 100 U.S. online retailers to gather its data.
