Toys R Us is giving mobile shoppers different ways to save during the Thanksgiving holiday weekend via promotions with foursquare and shopkick.

RedLaser partnered with Atlantic Records music artist Lupe Fiasco to promote his new album “Lasers” and drive pre-order sales by encouraging fans to scan a QR code.

Targeting holiday shoppers, eBay has added local shopping results from recently acquired Milo to its RedLaser bar code-scanning application for both Apple’s iPhone and Google’s Android.

On Cyber Monday mobile commerce sales from eBay shoppers in the United States increased 146 percent year-over-year, with California, Nevada, Maryland, Pennsylvania and Florida leading the way as the top mobile shopping states.

EBay has added QR code scanning and listings from eBay Marketplaces and Half.com to its RedLaser iPhone application to provide consumers with up-to-date product information on the go.

EBay has acquired RedLaser and plans to integrate the technology platform into its suite of mobile commerce services.
