Costco is facing scrutiny over its recent changes to membership rules, which have sparked controversy but are aimed at addressing parking issues at its locations. The company is also enhancing its e-commerce capabilities, with plans for an expanded buy-online-pickup-in-warehouse service, as stated by Millerchip. Analysts have raised concerns about Costco's valuation, with some labeling it as 'beyond overvalued.' The retail giant continues to position itself as a key player in the evolving consumer market, evidenced by its efforts to adapt to changing shopping habits and regional needs, including initiatives in Japan.
