In a number of cases, employees showed up to work and found the doors locked and a notice saying that the store would soon be liquidated. Walmart eventually told Business Insider that 63 Sam’s Club stores would begin liquidating across the country, including in Alaska, Arizona, California, Illinois, New York, Ohio, and Texas.According to Business Insider, the Sam's Club closings and plans to convert some stores into e-commerce fulfillment centers as announced in January 2018 are part of Walmart's growing commitment to online retailing that will allow it to better compete with rival Amazon.
