Cyber Monday sales were projected to set a record, jumping by nearly 20 percent to between $9.2 billion to $9.4 billion to become the biggest online shopping day in U.S. history, according to Adobe Analytics.

Adobe said online sales in states with at least two inches of snow got a 7 percent boost.
