Black Friday is setting new records online.

Online sales on Black Friday will hit $3.34 billion, up 22% on last year, and surpassing the $3 billion mark for the first time, according to estimates from software company Adobe Digital Index. That’s also an increase of nearly a $1 billion from just two years ago. More than one-third or $1 billion of Black Friday shopping will be done on mobile devices like a smartphone or tablet, while the rest will be done on computers, it said.

The two-day run-up to Black Friday was almost as busy. Thanksgiving Day totaled $1.93 billion in sales, up 11.5% on last year, slightly lower than the $2 billion anticipated, but adding up to $5.3 billion for both days. This was partly due to heavy discounting in the early hours of the holiday season. Sales on Wednesday, Nov. 23, totaled $1.57 billion, up 19% on 2015, $92 million more than Adobe estimates, which also contributed to less revenue on Thanksgiving.

“Black Friday may have just dethroned Cyber Monday’s position as largest online shopping day of the year,” says said Tamara Gaffney, principal analyst and director of Adobe Digital Insights. “Shoppers are still buying at higher than expected levels in the early morning hours of Small Business Saturday.” The highest price drops were seen for tablets (average discount of 25.4%), televisions (23.2%), toys (15%) and computers (11.6%).

Adobe’s latest insights are based on aggregated and anonymous data from 22.6 billion visits to retail websites, and claims to measure 80% of all online transactions from the top 100 U.S. retailers, the equivalent of $7.50 of every $10 spent with the top 500 retailers goes through Adobe Marketing Cloud. The average order value on Apple’s AAPL, -4.19% iOS devices ($142) outperforms Android devices ($130), the study based on actual transactions found.

In previous years, mobile shoppers liked to browse on smartphones but make their purchases on tablets. That changed in 2016. Mobile accounted for 55% of visits — smartphones (45%) tablets (10%) — and also 36% of sales so far — smartphones (25%) tablets (11%), while the rest of the traffic came from computers. Top selling electronics include the usual suspects: iPads, Samsung 4K TVs and LG TVs. Best-selling toys include drones, mini vehicles for kids and Lego sets.

The National Retail Federation, the industry group representing retailers, said last month that it expects sales in all of November and December — excluding autos, gas and restaurant sales — to hit $655.8 billion this year, including non-store sales of $105 billion. This represents an increase of 3.6% on last year, and significantly higher than the 10-year average of 2.5% annual increase and above the seven-year average of 3.4% since the economic recovery began in 2009.
