Part I — The story
The story
Sol Price invented the membership warehouse club — the model behind Costco and Sam's Club — and in doing so influenced modern retail more than almost anyone whose name the public doesn't know. With Price Club, he pioneered charging customers a membership fee to shop in no-frills warehouses stocked with a limited selection sold at razor-thin margins in bulk.
The genius of the model was that the membership fee, not the product markup, was the profit — so Price could sell goods at barely above cost, delivering genuine value that kept members loyal and renewing. His disciplined, ethical, value-obsessed approach directly inspired Costco's founders and was openly admired by Sam Walton and Jim Sinegal.
Price's warehouse-club invention — aligning the retailer's profit with delivering real value rather than marking goods up — is one of the most influential and widely-copied ideas in retail history.
