Sears is banking big on mobile shopping this holiday season and has upgraded its app with new features and offering mobile in-store consumers free shipping.

"In 2015 we've seen more than a third of our online traffic come from a mobile phone — a 46 percent increase from last year," said Leena Munjal, senior VP, customer experience and integrated retail, Sears Holdings, in an announcement.

"Mobile devices are so much a part of our members' lives and they're not only researching and sharing, they're also buying. So it's more important than ever to have a robust, simple-to-use shopping app with features and services that no other major retailer offers," Munjal added.

To further entice shopping activity Sears is offering a limited-time reward, for Shop Your Way members, and giving consumers $5 in points on purchases of $15 or more.

New enhancements to its mobile app include:

• In-vehicle pickup, return and exchange in five, guaranteed: Service lets members pick up, return or exchange their online purchases for free at any Sears store — guaranteed in five minutes or less — without ever leaving a vehicle.
• Complete layaway management: Shoppers can initiate a new layaway contract and make all payments via the Sears app. In-store, shoppers can now scan products directly from the app.
• eCoupons: Members get exclusive, personalized online and in-store discounts, no clipping necessary.
