Early Results Show Increase over Last Year's Cyber Monday Purchases

Up more than 20 percent compared to the same time period last year

Millions of Americans were expected to shop with a few clicks of their computers or mobile devices Monday to take advantage of special discounts offered on the first working day after the long Thanksgiving weekend.

Cyber Monday is projected to be the busiest day of the year for online shopping. The National Retail Federation, a trade group, predicts more than 131 million people will shop online, up about 2 percent from last year.

And research firm comScore expects Cyber Monday sales of $2 billion, up from about $1.47 billion last year. Online sales account for about 10 percent of total holiday spending, which is expected to grow about 3.9 percent to $602.1 billion for the months of November and December.
