Cyber Monday spending up 18 perecent from 2010

      Retailers say shoppers spent 18 percent more in 2011 on Cyber Monday, including a large uptick on mobile devices.

      NEW YORK (AP) Bad economy or no bad economy, shoppers were all over the Internet seeking Black Monday bargains following up on the enthusiasm for buying stuff over the long Thanksgiving weekend.

      Data from IBM Benchmark indicates online sales yesterday were up 18 percent from a year ago. And this year, it seems more people were willing to buy from mobile devices.

      Sales from mobile devices were up 7.4 percent. That suggests Americans have a growing comfort with using PCs, tablets and smartphones to shop.

      That's good news for retailers who can make up to 40 percent of their annual revenue during the holiday shopping season.
