Does Costco Do Price Adjustments? 30 Day Rule

Yes. Costco will match its own lower price within 30 days of purchase, but not other stores, and holiday promo items have a tighter window.

Bottom Line

Yes. Costco's customer service page says that if a purchase drops in price within 30 days of the date you bought it, it is eligible for a price match. That covers Costco's own prices only. Costco does not price match other businesses or retailers. It also does not match warehouse prices for Costco.com orders, because online prices take into account shipping and handling. Items with promotional limits qualify up to the limit quantity. Resellers must buy during the promotion dates to get the promotional price. Precious metals are not eligible. Costco reserves the right to deny a request at its sole discretion. The holiday catch: for items with specific sale dates, such as Holiday Savings Promotions, you must submit the request within both the active promotional dates and 30 days of purchase. Requests made after the promotion has ended may be denied.

Follow-up questions

How do I request a price adjustment on a Costco.com order?
Use the Request a Price Match button on Costco's price match page and complete the form. Once a request is approved, Costco says credits are typically issued within 5 to 10 business days to the original form of payment. The same page also lets you check whether a promotional price was already deducted from your order.
What if I bought the item in a Costco warehouse?
Costco's page says to ask at the Returns counter of the warehouse where you made the purchase. It does not describe an online form for warehouse purchases. Tires bought in a warehouse work the same way: visit the warehouse where you bought them.
Will Costco match another store's lower price?
No. Costco says it does not price match other retailers because it already offers competitive prices at the point of purchase. If you are not satisfied with a purchase for any reason, Costco says it will accept the item for a full refund, though limitations apply and there are exclusions.
Do tires and installed home products qualify?
Tire and wheel purchases qualify for a price match if all other conditions are met. For Special Order Kiosk and Home Improvement installed products, promotions are based on qualifying products, the signed contract date and/or the price before tax. Costco says to contact your Costco authorized dealer to find out whether your project qualifies.

What to do

Keep the purchase date for big holiday buys and recheck the price before the promotion ends. Then file the request online or at the Returns counter where you bought the item.
