Cyber Monday is the Internet's answer to Black Friday, the American retail holiday where stores discount just about everything and throw open their doors to crowds of shoppers at midnight following Thanksgiving. Of course, it's been years since Black Friday started on Friday. Many retailers, including Toys "R" Us and Walmart, open on Thanksgiving.
Toys "R" Us is touting, among its steepest Cyber Sunday discounts, the Thomas & Friends Wooden Railway Gold Mine Mountain Set at half price, for $80. On Cyber Monday the retailer will have the Barbie Malibu Dream House for $95, down from $135, and the Tonka 12-volt Dump Truck Ride-On for $200, down from $350.
Amazon is offering discounts for a wide variety of products including electronics ($200 off Lenovo laptop,) toys (60% off Ginormous Outward Hound Hide-A-Squirrel,) home (60% off Singer sewing machine) and sports (50% off Elliptical machine.)
Walmart also has a wide variety of cyber deals, including discounted drones, which will be among the hottest products this year.
