Costco Price Adjustment Policy (2026 Guide)

Published August 20, 2026 · Reviewed August 21, 2026 · 6 min read · By Recoup It Editorial Team

The short version: Costco says a non-resale purchase may qualify when its price drops within 30 days of purchase. If the lower price is part of a promotion with specific dates, the request must also be made while that promotion is active. Costco decides every request.

1. What Is a Costco Price Adjustment?

A price adjustment, which Costco currently calls a price match on its customer-service page, is a request for the difference when Costco lowers its own price after a purchase. For non-resale purchases, Costco says the price must drop within 30 days of the purchase date.

This is different from matching another retailer’s price. Costco says it does not price match other businesses, and it reserves the right to decide whether a request qualifies.

2. Warehouse vs. Costco.com Rules

A crucial rule to understand is that Costco separates warehouse purchases from Costco.com purchases:

Purchase Channel	Where to Request	How It Works	What Happens Next
Warehouse Purchase	Returns Desk at the warehouse where bought	Ask about a possible price match for the purchase	The warehouse reviews and decides the request
Costco.com Order	Online Request a Price Match form	Complete the requested order and item information	If approved, Costco says the credit is typically issued within 5 to 10 business days to the original payment method

Important: Costco does not match a warehouse price for a Costco.com purchase. Costco explains that online prices can include shipping and handling costs that do not apply in the warehouse.

3. Common Exceptions & Limitations

Promotion dates: If a sale has specific start and end dates, the request must be made while the promotion is active and within 30 days of purchase.
Resale purchases: Eligibility is limited for resale members and products. Product and promotion limits can also apply.
Other retailers: Costco does not match prices from other businesses.
Warehouse and online prices: A warehouse price is not matched against a Costco.com purchase.
Precious metals: Costco says precious metals are not eligible for a price match or promotion.
Final decision: Costco reserves the right to deny a request and may show additional restrictions at the point of purchase.
