The retail industry continues to evolve at a fast pace into something where brick-and-mortar stores no longer stand independently of digital, mobile and social technologies. Store retailers are losing sales as consumers use mobile devices and social networks while they're physically in-store to seek advice, reference product information and online reviews, and, ultimately, purchase products online or even at another store. Online retailers like Amazon.com and Zappos.com are taking advantage of this trend to lure consumers away from more traditional retailers.
