Since June 30, 2025, Costco has offered Executive members an extra hour to shop at many warehouses, and by September the perk expanded company-wide. Traffic data shows that the extended hours are already reshaping shopping patterns, with measurable impacts on both visit timing and dwell times.
Executive Early Hours Reduce Peak-Time Crowding
The chart below compares Costco visit patterns between April and June 2025, before extended Executive Member hours were introduced, with July and August 2025, when most warehouses began offering exclusive early access from 9:00 AM to 10:00 AM. The additional morning hour appears to have encouraged some Executive members to shift their trips earlier in the day, which in turn reduced traffic concentration during late-morning and afternoon peaks.
This redistribution helps create a more balanced flow of visitors, likely improving the shopping experience for members overall.
Shifts in Visit Duration
The impact of early openings extends beyond when members shop – it also affects how they shop. The chart below, which tracks visit lengths before and after the introduction of early Executive openings, shows that the share of Costco visits lasting 30 to 45 minutes increased in July and August while the share of visits lasting 45 to 60 minutes fell.
This shift suggests that early-access shoppers are more purposeful and efficient, taking advantage of lighter crowds and easier store navigation. Importantly, Costco did not assign additional staff hours to cover the new morning window – a decision that seems to be validated by the data. With members shopping more efficiently, the company managed to enhance customer experience without increasing operational costs.
A Win-Win for Members and Retail Operations
By extending special hours to Executive members, Costco not only rewards high-value customers but also reduces congestion during traditional peaks. The smoother distribution of visits and more efficient shopping trips underscore how strategic adjustments to operating hours can drive meaningful changes in consumer behavior.
As retailers navigate evolving shopper expectations, Costco’s example highlights the power of data-driven scheduling to enhance both customer satisfaction and operational efficiency.
