Business Model
What each company does and how it makes money
PriceSmart operates membership-based warehouse clubs in Latin America and the Caribbean, offering U.S.-style bulk shopping for groceries, household goods, and services like optical and tire centers. It generates revenue primarily from membership fees — which provide recurring income — and merchandise sales across its physical clubs and Click & Go e-commerce platform. The company's moat lies in its first-mover advantage and established brand recognition as the dominant membership warehouse operator in underserved emerging markets where Costco and Sam's Club have limited presence.
Walmart is the world's largest retailer operating a vast network of physical stores and e-commerce platforms. It generates revenue primarily through retail sales — with Walmart U.S. contributing about 65% of total revenue, Walmart International around 20%, and Sam's Club membership warehouse clubs roughly 15%. Its key competitive advantage is massive scale and supply chain efficiency, enabling everyday low prices that competitors struggle to match.
Costco operates a global chain of membership warehouse clubs that sell a wide range of merchandise at low prices to members. It generates revenue primarily from membership fees — which account for roughly 70% of operating income — and merchandise sales, with a razor-thin markup on goods. The company's moat lies in its extreme operational efficiency, massive buying power, and fiercely loyal membership base that renews at over 90% rates.
