  • Cost reduction: This strategy minimizes the costs associated with managing extensive inventory and reduces the need for complex storage systems.
  • Faster turnover: With fewer choices, Costco can achieve faster inventory turnover, ensuring fresh products and avoiding excess inventory costs.

4. Minimal Marketing Expenses

Unlike many retailers, Costco relies less on traditional advertising and marketing campaigns, allowing them to allocate more resources to providing value to their customers.

  • Word-of-mouth reputation: Costco's focus on providing quality products at low prices has generated a strong word-of-mouth reputation among customers.
