We explore how Costco uses technology not as a gimmick, but as a strategic enabler—streamlining operations, optimizing inventory, and enhancing the customer experience without sacrificing its famously low prices. From data-driven supply chains to checkout efficiency, this episode uncovers how simplicity and discipline can beat complexity.
