Holiday shoppers eager to snag big discounts turned to the internet in record fashion this week.

Adobe, which tracks online retail transactions, says consumers spent $3.34 billion shopping online on Black Friday Friday, a 21.6 percent increase from the same day last year.

The firm said more than ever before, shoppers used their mobile devices to dial up deals online, and mobile purchases surged 33 percent on Black Friday to $1.2 billion.

Even so, many shoppers across the U.S. and in Chicago still ventured to stores and malls looking for deals. The Mall of America in Minnesota, which opened 24 years ago, reported that Friday was the highest traffic day it can recall.

In Chicago, demonstrators disrupted Black Friday shopping on the Mag Mile to call for more accountability for Chicago police for the second year in a row.

Adobe also found Americans had already spent $25.5 billion online this month, a 3.5% increase from last year. The top-selling items, Adobe says, include a slew of electronics and toys, like Samsung 4K TVs, iPads, electric scooters and Lego sets.
