Strong Cyber Monday Sales Expected

An estimated 129.2 million shoppers say they will head to retailers' websites today, up from 122.8 million who shopped last year, according to a Shop.org survey. This follows record levels of online spending over the Black Friday weekend.

Special promotions will be more widespread this year--85 percent of retailers will have online deals for Cyber Monday, up from 78 percent in 2011.

Nearly half the retailers (44 percent) will lure shoppers by offering free shipping.

Smartphones and other mobile devices will play a big part in online shopping today. A projected 20.4 million shoppers, up 14.4 percent from 2011, plan to shop with their devices. As recently as 2009, only 3.6 million used mobile devices to shop on Cyber Monday.

The majority of Cyber Monday shoppers, 113.7 million people, will still make purchases from their home computer but nearly 16 million will also use their computers at work to shop this year.

Lunchtime will be a popular time for shopping today, but the entire day will be active. According to the survey, 44.4 percent plan to shop early in the morning, 36.8 percent plan to shop in the late morning and 29.2 percent will shop in the early evening.
