Internet marketing and product brokerage company Market America is integrating with recently acquired comparison shopping site Shop.com to create a new mobile social shopping destination.

Buy.com is letting holiday shoppers compare bricks-and-mortar store pricing to online discounts via a bar code scanning and speech recognition mobile application.

PayPal, an eBay company, has rolled out a mobile version of its Express Checkout service that lets merchants offer the same PayPal experience for their on-the-go customers.

Buy.com has enhanced its mobile shopping Web site due to the strong growth in traffic the destination has experienced.
