how late is costco open

Costco's closing time varies by location, but many warehouses are typically open until around 8:30 PM to 10:00 PM on weekdays. For example, some Costco locations operate from approximately 6:00 AM to 10:00 PM on weekdays, 6:00 AM to 8:30 PM on Saturdays, and slightly shorter hours on Sundays (around 6:00 AM to 7:30 PM or 7:00 AM to 6:00 PM). Night shift employees might work until about 10:00 or 11:00 PM, but the store itself generally closes earlier than that. Specific hours can differ by warehouse and day of the week, and exclusive early shopping hours apply for Executive Members in some stores, with warehouse openings as early as 9:00 AM. It is advisable to check the exact hours for the local warehouse using Costco's store locator or app for the most accurate and current information.
