The flip side is that the items on offer, including promotional offers, are limited to supplies on hand. We’re unable to guarantee how long those supplies will last. To secure the best prices for our members, Costco.com purchases all items in bulk. Once inventory sells out, our buyers will negotiate for additional inventory.

You can also browse through the drop-down menu of departments on the Costco.com homepage, shop by categories and locate products that match what you’re looking for. Please keep in mind that the items available online are unique to Costco.com and may not be carried in your neighborhood Costco warehouse.

You can use the Costco App to check warehouse inventory. Head to our mobile app page to learn more!. To use our customer service page instead, follow these steps:
