Does Costco match other stores?

No. Costco does not match other stores' prices.

If you miss the window

If a store won't adjust the price but the item is still inside its return window, you can often return it and buy it again at the lower price. Check the return rules and any restocking fee first, and buy the new one before returning if stock is low.

Credit card price protection

Most big card issuers dropped price protection between 2018 and 2020. Capital One still offers it on its Discover-network Venture, Savor and Quicksilver cards (120 days, up to $250 an item), and a few others, like some Wells Fargo Visa Signature cards, still do. Your card's Guide to Benefits is the final word.
