Speaking at Fortune’s Most Powerful Women dinner, Rosalind Brewer said she is outflanking chief channel rival Costco with investments in digital retail, with an emphasis on mobile. And in a been-there-done-that moment, she also warned Amazon, which is beefing up its private-label assortment, that house brands are far easier said than done.
“Walmart, the world’s largest retailer, is used to being the big dog. So when Rosalind Brewer took over the company’s Sam’s Club division in 2012, it put her in an odd position. Walmart’s warehouse club business is No. 2, second in size to industry rival Costco .”
