Dialing up deals: Black Friday online sales hit new high

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 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. still ventured to 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.
