Costco Promo Codes & Offers in November 2026

Q: How do I get free shipping?

Many Costco items include free standard shipping. Look for items marked “Free Shipping” on the product page. If an item doesn’t show that label, shipping charges may apply. Express shipping usually costs extra. For grocery orders, 2-Day delivery item surcharges are generally waived on orders of $75 or more.

Q: Does Costco offer a student discount?

Yes. Costco offers a student discount through UNiDAYS for eligible new members. Rather than giving students a percentage off, Costco offers a $20 Digital Costco Shop Card with a Gold Star membership or a $40 Digital Costco Shop Card with an Executive membership. To qualify, you must verify your student status through UNiDAYS and complete a new membership signup.

Meet your expert

As a savings expert, Costco’s weekly sales and price cuts always catch my attention. Hi, I’m Pat, an editor at Coupons.com since 2021. I add the deals and savings tips you’ll find on this page. I also hand-test and verify every code, and I work with the Costco affiliate team to help shoppers find strong discounts on everyday purchases.

My top advice is to check Costco’s Treasure Hunt section. It features member-only pricing and limited-time sales. I’ve found savings of up to $1,000 on electronics and furniture there.

Frequently asked questions about Costco

Can I refer a friend to Costco and get a discount?

Yes. Refer a friend to Costco, and you both get a Digital Costco Shop Card when your friend signs up for a new membership. The reward is a $20 Shop Card for a Gold Star Membership or a $40 Shop Card for an Executive Membership. To qualify, both people must mention the Refer-a-Friend program at the membership counter at a U.S. Costco location. You must also provide a valid email address and enroll in auto-renewal of your annual membership at signup. You can expect your Digital Costco Shop Cards via email within two weeks. A separate form is required for each referral. The offer is limited to one per household and expires December 31, 2026.

Are there savings from their credit card?

Absolutely. The Costco Anywhere Visa Card by Citi offers cash back on eligible purchases. Once set up, you’ll earn 5% back on the gas you buy at Costco. You’ll earn 4% back on other eligible gas purchases and EV charging for the first $7,000 spent each year, then 1% after that. You’ll also get 3% back on restaurants and eligible travel, 2% back on Costco and Costco.com purchases, and 1% back on everything else. The card also has no annual fee with your paid Costco membership, works as your membership card, and has no foreign transaction fees.

How do I get free shipping?

Is there a military discount?

Yes. Costco offers a military discount through Military.com for new members. The discount is available to active duty service members, military retirees, veterans, Reserve and National Guard members, and their dependents. To qualify, first verify your military status through Military.com. Then join Costco and enroll in auto-renewal of your annual membership. After verification, you will receive a $20 Digital Costco Shop Card with a Gold Star Membership or a $40 Digital Costco Shop Card with an Executive Membership.

Does Costco offer price matching?

No. Costco doesn’t price match other retailers. But some Costco purchases may qualify for a price match if the item goes on sale within 30 days of purchase. This policy applies to eligible Costco and Costco.com purchases, but Costco does not match warehouse prices to Costco.com prices. Holiday promotions may have different rules, and precious metals are excluded. To qualify, request a price match within 30 days of purchase. For special sale dates, the request must also be made while the promotion is still active.

Does Costco offer a student discount?

Get Costco emails for member deals and seasonal sales

Sign up for Costco's email newsletter for the latest offers and upcoming promotions. You'll find members-only discounts, limited-time deals, and seasonal sale alerts. In August 2026 emails, we saw them promoting a "Spend & Save" offer on appliances. For example, you spend $1499 or more and get an extra $200 off. Spend $1999 or more for an extra $300 off. Or spend $2499 or more and receive an extra $500 off.

Costco tends to email new sitewide savings at the start of each month, and they also send early details before bigger sales go live. That included their Labor Day mattress sale in September, with up to $700 off top brands like Tempur-Pedic, Novaform, Purple, Sleep Number, Stearns & Foster, and more.
