Costco Promo Codes & Coupon Book

1. Plan your trip around the member-only instant savings

   Dollars off listed items, no codeLow effortMembers, in the warehouse or online

   Costco posts its Member-Only Warehouse Savings for a fixed run of dates, item by item: each one is marked Warehouse Only, Online Only or Warehouse & Online, and most carry a per-household limit. On Costco.com there's no coupon code to enter — the saving is taken off automatically at checkout. The same savings booklet goes by mail to the Primary Member of active shopping accounts, one copy per address.^{[10, 11, 12, 13]}

   1. Open the Warehouse Savings page on costco.com and note the valid dates at the top.
   2. Check each item's label (warehouse, online or both) and its household limit.
   3. Buy before the last valid day — Costco doesn't honor instant savings after it.

2. Upgrade to Executive only if your spending covers the $65

   About 2% back, up to $1,250 a yearLow effortHouseholds spending around $3,250+ a year at Costco

   Executive costs $130 a year — $65 more than Gold Star or Business — and pays back roughly 2% of eligible pre-tax purchases, capped at $1,250 for any 12-month period. On Costco's own table, $3,252 of purchases a year earns about $65, the price of the upgrade. Gasoline, tobacco, Shop Cards, cellphones, food court meals, membership fees, tax and shipping don't count, and nothing bought before the upgrade earns the reward. Executive members also get a $10 credit each month on one Same-Day order of $150 or more.^{[1, 2]}

3. Ask for the difference when a Costco price drops within 30 days

   The drop credited to your paymentSome effortCostco.com orders and warehouse purchases

   If an item you bought gets cheaper within 30 days of the purchase date, it qualifies for what Costco calls a price match, up to any promotional item limit. When the lower price comes from a dated promotion, the request has to be made while that promotion is still running as well as within the 30 days. Approved credits on Costco.com orders typically reach the original payment method in 5 to 10 business days.^{[8, 9]}

   1. Under Orders & Returns, open the order summary to see whether the promotion was already deducted.
   2. For an online order, use the Request a Price Match button on Costco's help page.
   3. For a warehouse purchase, ask at the Returns counter of the warehouse where you bought it.

4. Join online with auto renewal to collect a Shop Card

   $40 (Executive) or $20 (Gold Star)Low effortNew members, or no membership in 18 months

   As of Oct 16, 2026, Costco's join page offered a Digital Costco Shop Card — $40 with Executive, $20 with Gold Star — to new members who sign up online and set up auto renewal on a Visa card or Mastercard debit card, with no end date shown. Renewals and upgrades don't qualify, nor does anyone who held a membership in the last 18 months, and the card is emailed within 2 weeks. The page sends students (through UNiDAYS) and teachers, health workers, first responders, government employees and military (through SheerID) to this same new-member offer.^{[1, 18, 19]}

5. Compare warehouse, Costco.com and Same-Day prices

   Skip the delivery markupsSome effortAnyone ordering for delivery

   Costco.com prices build in shipping and handling, so they can be higher than the warehouse's, and Costco won't adjust an online purchase down to a warehouse price. Same-Day Delivery prices are marked up above your local warehouse to pay for Instacart's service, with a $35 order minimum. For non-perishables, CostcoGrocery 2-Day Delivery adds $3 per item unless the order reaches $75 before tax.^{[7, 8, 14]}

  Ends Oct 18, 2026

1. Nonmembers pay 5% more online

   Some Costco.com items can be bought without a membership, but nonmembers pay 5% more than members. In the warehouse, everything except prescriptions needs a paid membership.^{[4, 16]}

2. Instant savings stop on the last valid day

   Costco says its vendor agreements limit instant savings to the dates shown, so they aren't honored afterwards. They also can't be combined with other savings, and household limits apply where marked.^{[10, 12]}

3. The 2% Reward is spent in the warehouse

   It arrives as a paper certificate with your renewal statement and is redeemed at a warehouse register — not at self-checkout. To use it on Costco.com, buy a Costco Shop Card with it in the warehouse and pay online with the card.^[3]

4. Auto renewal bills on the 1st of your renewal month

   With auto renewal, your card is charged on the first day of the month your membership renews. To stop it, cancel at least 72 hours before that day — in your Costco account, at a membership counter or through Member Services.^[4]

5. Costco Next is gone

   Costco's help center says Costco Next storefronts are no longer available. For returns or warranty questions on an earlier Costco Next order, contact that vendor directly; Costco lists their phone numbers and emails.^[17]
