Overview
- Costco confirmed it will close all warehouse locations on Memorial Day, May 25, 2026, and will resume normal hours the next day.
- Shoppers who need last-minute food, drinks or party supplies are advised to use competitors such as Walmart, Target and Kroger, which are expected to operate regular holiday hours.
- Costco requires a paid membership to shop in-store but allows nonmembers to buy prescriptions or use a Costco gift card for purchases.
- The chain offers two main membership tiers—Gold Star at $65 per year and Executive at $130 per year—and Executive members get earlier shopping windows on weekdays and weekends.
- This closure reflects Costco’s long-standing policy of observing seven annual holidays when warehouses close, a practice that sets it apart from many big-box and grocery chains.
