A tornado destroyed a "Sound of Music" store (Best Buy's original name), forcing a massive, open-floor "Best Buy sale" to liquidate damaged inventory. This accidental format proved so successful that it became the foundation for the company's modern, customer-centric retail experience.

PriceSmart successfully replicates the Costco model in Central America, the Caribbean, and South America—regions where there are no other major club store competitors. This 'blue ocean' strategy allows it to capture a large, underserved market segment.

Following lessons from Sam Walton and military history, PriceSmart prioritizes owning real estate and distribution centers. This control over its supply chain is a critical moat that ensures stability, manages costs, and provides a decisive advantage in unpredictable environments.

The commodity product bleach, where Clorox holds 60% market share despite costing 40% more, shows how powerful branding builds trust. This model is transferable to home services, a 'perceived commodity,' enabling companies to build market share and pricing power through brand familiarity and trust.

Against his company's wishes, Kroc would tell restaurant owners to stock up on paper cups before a price increase. This prioritized the long-term relationship and built immense trust, proving he was on their side. It's a powerful lesson in choosing relationships over short-term transactional wins.

Reflecting its founder's DNA, the company deliberately avoids squeezing suppliers for the lowest price. Instead, it partners with local producers to help them scale, building a reliable, long-term supply chain that grows with the business and fosters goodwill.

Maximizing profits in a crisis, such as a hardware store hiking shovel prices during a blizzard, ignores the powerful economic force of fairness. While rational by traditional models, such actions cause public outrage that can inflict far more long-term brand damage than the short-term profits are worth.

Contrary to typical advice to grow fast and be asset-light, PriceSmart expands at a deliberate, controlled pace. It focuses on owning its real estate, which provides long-term control, operational flexibility, and a more durable business model in its target markets.

Home Depot became the default shopping destination for so many customers that manufacturers faced a choice: sell through Home Depot or lose access to consumers who wouldn't seek them elsewhere. This created a powerful network effect where scale attracted key suppliers, which reinforced customer loyalty and solidified their market dominance.
