After offering online deals for days, retailers are rolling out more promotions for Cyber Monday, hoping to keep people buying.
Shoppers are expected to spend $6.6 billion online on Cyber Monday, up more than 16 percent from a year ago, according to Adobe Analytics, the research arm of software maker Adobe.
More people will use their phones: Adobe says web traffic from smartphones and tablets is expected to top desktop computers for the first time this year.
Target and Toys R Us are offering 15 percent off most items on their sites. Walmart.com has tripled the amount of items available for sale from last year.
Amazon will have similar deals on its gadgets as it did on Black Friday but offer newer ones on toys and other items.
