Shoppers take to their smartphones for Cyber Monday deals

After offering online deals for days, retailers are rolling out even more promotions for Cyber Monday, hoping to keep people buying stuff on their smartphones or computers.

Shoppers are expected to spend $6.6 billion on Cyber Monday, up more than 16 percent from a year ago, according to Adobe Analytics, the research arm of software maker Adobe. And more people will be picking up their phones to shop: Web traffic from smartphones and tablets is expected to top desktop computers for the first time this year, Adobe said.

Amazon -- which Bain & Co. says is expected to capture 50 percent of all online sales growth -- will offer similar deals on its gadgets as it did on Black Friday, but offer new deals on Lego sets and Hasbro games.

Deals which are available now on Amazon include:

Echo Show, $179.99 (regular price: $229.99)

Amazon Tap, $79.99 (regular price: $129.99)

Fire HD 8, $49.99 (regular price: $79.99)

Fire 7, $29.99 (regular price: $49.99)

As part of their Cyber Monday deals, 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.

The shift to online shopping has been noticeable at some stores since the holiday shopping season kicked off.
