What Is the World’s Busiest Costco on Oahu? MOJO Branding

Sales Broker

MOJO Branding takes a closer look at the Iwilei Costco on Oahu Island, Hawaii, widely known as the busiest Costco location in the world. Costco estimates that one in four Oahu residents are Costco members, an incredible statistic for an island with a population of over 950,000 people. With locals, tourists, and military families shopping daily, it’s easy to understand why foot traffic at this location is nonstop from open to close.

While there are four Costco warehouses on Oahu, the Iwilei location stands out dramatically. It generates more than twice the annual revenue of an average Costco warehouse, making it a prime environment for brands looking to test, launch, or scale products through live selling and road shows. High volume, fast decision-making, and repeat visits create ideal conditions for strong sales performance.

MOJO Branding recently consulted on and managed a road show at the Iwilei Costco, overseeing strategy, staffing, and execution. The results spoke for themselves. Sales exceeded plan, member engagement was high, and the client walked away thrilled with the outcome. With the right approach and an experienced sales broker, even the busiest Costco in the world becomes a powerful growth opportunity.
