Walmart is starting its cyber Monday holiday shopping sales a day early. The retail giant says it will launch its online holiday shopping sales on Sunday, November 29th. Walmart typically started its Cyber Sales on the Monday after Thanksgiving. But the company says faster internet to more homes and smartphones makes the move to Sunday more practical. Walmart says it will quadruple its number of Cyber Monday specials this year. About 90-percent of those deals come with free shipping.
