Costco typically restocks its shelves daily at around 4 a.m. before the warehouse opens. It replenishes products such as fruits, vegetables, meats, cleaning supplies, alcohol, personal hygiene items, and more. During the holiday period, Costco is known to stock shelves 24/7.

Does Costco Restock Every Day? 

Yes, Costco does restock its merchandise every day. At 4:00 a.m., Costco logistics teams unpack and restock more oversized items, clean up the departments, face out the new merchandise, and dispose of cardboard and other packing materials.

Additionally, all restocking items are present in the warehouse and stored on pallets, but due to safety concerns, no major restocking can occur during the day.  

After the initial stocking each morning, Costco employees continue to stock smaller items, essentials, and food goods throughout the day at a slower pace.

The only 24-hour restocking occurs during major holidays like Christmas, Thanksgiving, or Easter. 

What Items Are Restocked? 

Costco restocks all its merchandise daily, including baby goods, books, cleaning supplies, clothing, electronics, groceries, hygiene items, garden and lawn equipment, large appliances, and more.

Though Costco restocks daily, any hot items will be gone early on due to demand. To ensure you get an item, arrive in the first hours of Costco being open to the public.  

What Items Are Not Restocked? 

Everything is restocked each morning, but only the essential or specialty items will continue to be restocked during business hours.

If there is a shortage or an issue with the manufacturer, Costco will try to meter out those items so that everyone has a chance to purchase them. 

However, if you see an asterisk in the top right corner of a price tag in-store, it indicates that the item will not be restocked, is being discontinued by the manufacturer, or Costco has decided to stop carrying it in the future.

If one of your favorite products has an asterisk on the price tag, it might be worth stocking up! 

How Do I Know If Something Is In Stock At Costco? 

You can find out if an item is currently in stock at your local Costco warehouse by phoning the store and choosing the phone menu option for Membership.

It helps to have either the item number or product description handy so Costco Member Services can quickly check availability.

Alternatively, check Costco.com for live updates on inventory levels. Just remember that some items are not available online and only for in-store purchases, and vice versa. 

What Day Does Costco Get Shipments?

Costco warehouses receive 3 to 6 initial loads every morning, which are hurried to the floor and used for inventory restocking.

It can differ by location, but shipments generally come daily, so employees will work to restock essential and specialty items during their shifts.

However, some smaller Costco stores that don’t get the same customer demand may get shipments a few times a week, generally on Monday, Wednesday, and Friday.  

What Is The Best Day To Shop At Costco? 

Costco is prone to crowds and busy customer rush hours. However, the best times to shop at Costco are weekday mornings between 10:00 a.m. and 11:00 a.m., as you can avoid the expected chaos on busy weekends.

Avoid shopping on Monday mornings—it is a favored time for parents to restock for the week or for senior shopping day deals, and products will be flying off shelves. 

For more weekday options, shop on Tuesday, Wednesday, and Thursday afternoons between 3:00 p.m. and 5:00 p.m. to avoid the lunchtime rush and to get your shopping done before people show up after their workday.

Some Costco managers also recommend visiting the store within an hour of their 8:30 p.m. closing during weeknights to avoid crowds and spare shelves.

Does Costco Restock Out-Of-Stock Items Online?

When the item is once again available for purchase, it will re-appear on Costco.com. Costco fulfillment depots keep the website entirely up to date throughout the day, so check frequently for changes to stock and updated inventory.
