Historically, retailers have found it difficult to combat the dominance of the mega-retailers during periods of high-volume selling. By all estimates, this holiday season, which is projected by NRF to exceed last year’s record breaking volume levels, will be no different. Amazon, WalMart, Apple and Google have all made moves to leverage their not inconsiderable customer share of attention to enhance their own return with key investments in online selling, logistics, retail analytics and loyalty programming.
