Walmart is hosting its first seller summit businesses that are part of its third-party marketplace. LAS VEGAS — Walmart is looking for new ways to woo sellers to its third-party marketplace, as it pushes to drive more online sales and close a wide gap with rival Amazon . Walmart also hired another Amazon veteran, Jare' Buckley-Cox, as vice president of Walmart Fulfillment Services. Walmart is the nation's largest retailer, but it lags far behind Amazon in online market share and e-commerce sales. Walmart's annual online sales were less than one-fifth of Amazon's last year, according to Insider Intelligence.
