Costco Price Adjustment Policy: 30-⁠Day Rule, Exclusions & How to Request

Bought a TV at Costco and saw it on sale soon after? You may be able to get the difference back. Costco calls this a price match on its help center, but it works like a classic price adjustment: Costco compares the price you paid with its own lower price, not with other stores. Here are the rules from Costco's official page.

The 30-day rule

For members other than resellers, purchases that drop in price within 30 days of the date of purchase are eligible for a price match ¹. If the lower price comes from a promotion with a quantity limit, you're eligible only up to that limit ¹.

Costco doesn't promise to approve every request: it reserves the right to deny a price match at its sole discretion and says it may restrict the policy in the future, with restrictions shown at the point of purchase ¹.

Sales with set dates (like Holiday Savings)

For items with specific sale dates – Costco gives Holiday Savings promotions as an example – you must submit the request both while the promotion is active and within 30 days of your purchase date ¹. Requests submitted after the promotion ends may be denied ¹, so don't wait until the sale is over.

What doesn't qualify

• Other retailers' prices. Costco does not price match other businesses or retailers ¹.
• Warehouse prices for online orders. If you bought on Costco.com, a lower warehouse price doesn't count, because online prices include shipping and handling costs that warehouse purchases don't have ¹.
• Precious metals, which aren't eligible for price matches or promotions ¹.
• Resale purchases. Eligibility is limited to non-resale members and products; resellers must buy during the valid promotional dates to get the promotional price ¹.

Tires and wheels do qualify if all the other conditions are met ¹.

How to request a price adjustment

Costco.com orders: use the "Request a Price Match" button on Costco's price match help page and complete the form. Once approved, the credit typically goes back to your original form of payment within 5 to 10 business days ¹.

Warehouse purchases: ask at the Returns counter of the Costco warehouse where you made the purchase ¹. For tires and wheels bought in a warehouse, Costco likewise directs you to the warehouse where you bought them ¹.

Special orders and installed products

Special Order Kiosk and home-improvement installed products follow promotion rules based on the qualifying product, the signed contract date and/or the pre-tax price ¹. Exceptions that qualify you for extra Costco Shop Card value are limited to the 14 days before and 14 days after the official promotion dates, and Shop Card promotions can't be combined with other manufacturer promotions or incentives ¹. Costco asks you to contact its authorized dealer to check whether a project qualifies ¹.

Price adjustment vs. returning the item

A price adjustment keeps the product in your hands and refunds the difference. If you'd rather return the item instead, Costco's return policy is separate – most products fall under its satisfaction guarantee ², while electronics have a 90-day window ². See our Costco return policy guide for those rules.

Quick tips

• Note your purchase date: the 30-day clock starts there, not at delivery ¹.
• For dated promotions, submit before the promotion ends ¹.
• Keep your order number handy for the online form, and your receipt for the warehouse Returns counter.
