Editing Costco stock (section)

=== Overview of Costco's Business Model ===
Founded in 1983 by James Sinegal and Jeffrey Brotman, Costco operates a membership-based retail chain offering a wide range of products including groceries, electronics, clothing, and more, at competitive prices. The warehouse model encourages bulk purchases and offers substantial savings, which has helped Costco build a loyal and growing customer base.

Costco’s business model relies heavily on its membership fees, which contribute a significant portion of its revenue and profit. Members pay an annual fee to shop at Costco locations, which has resulted in an incredibly steady and predictable revenue stream. This model allows Costco to sell products at lower margins while still maintaining strong profitability.
