Top ways to save at Costco

📨
Unlock a welcome offer

Join the Costco email or text list and you'll often get an extra discount on your first order on top of any code here.

🗓️
Time it with the big sales

The deepest Costco markdowns land around Black Friday, Cyber Monday and end-of-season clearances. Bookmark this page before those events.

🚚
Clear the free-shipping bar

If you're a few dollars short of free delivery, add a small item, it's usually cheaper than paying shipping.

⚡
Try the top-scored code first

Our codes are ranked by Health Score. Start with the highest one, it's the most likely to apply, and vote so others know what worked.

Costco coupons: FAQ

Does Costco have a promo code right now?

Yes. KlipDeals is tracking 23 live Costco offers this June 2026, including 20 promo codes and 3 deals. The highest-confidence code currently scores 65/100.

How do I use a Costco promo code?

Click "Show code" to reveal it and open costco.com in a new tab. At checkout, paste the code into the promo or discount box and apply it before you pay. The discount updates your order total instantly when the code is valid.

How often are Costco codes updated?

Continuously. Codes are re-checked in real time and each one carries a Health Score that blends real checkout outcomes, shopper votes and freshness, so the most reliable Costco offers always rise to the top.

Why didn't my Costco code work?

Codes can expire, be single-use, or exclude sale items and certain brands. If one fails, tap "👎 No" to warn other shoppers and try the next highest-scoring code, those are most likely to apply.

About Costco savings

Costco (costco.com) offers are tracked on KlipDeals and scored for confidence so you can shop without the guesswork. We surface the highest-scoring promo codes first and demote anything that stops working, based on real checkout outcomes and shopper votes. Codes change often, so check back before checkout, and tap a thumb to tell the community what worked.
