Does Costco Price Match? What Actually Works

Quick answer: No — Costco does not price match other retailers like Amazon, Walmart, or Best Buy, and it generally won't match a competitor's lower price. What Costco does offer is a price adjustment: if something you bought at Costco drops in price at Costco within 30 days, you can claim the difference back. So the honest answer to "does Costco price match?" is that Costco doesn't match competitors, but it does refund its own price drops — which, for most members, is the more useful policy.

Key takeaways

• Costco does not price match competitors — no matching Amazon, Walmart, Target, or Best Buy prices.
• Costco does do price adjustments: a refund of the difference if a Costco item drops in price within 30 days of your purchase.
• "Price match" and "price adjustment" are different things — most people searching "Costco price match" actually want the price adjustment.
• You claim adjustments in-warehouse or via the online price adjustment form, within the 30-day window.
• The hard part is catching the drop in time — which is where a tracker like CostRefund helps.

Does Costco price match competitors?

No. Unlike Target, Walmart, or Best Buy — which will match a lower advertised price from certain competitors — Costco does not have a competitor price-match policy. If you find the same item cheaper at Amazon, Costco won't match that price at the register or refund the difference.

Costco's pricing model is built differently: the whole pitch is that its everyday warehouse prices are already low because of membership and bulk buying, so it doesn't run a match-a-competitor program the way traditional retailers do. If you want a competitor-matching comparison, we cover how Costco's approach compares to Target and Walmart.

What Costco does instead: the 30-day price adjustment

Here's the part that actually saves you money. Costco has a price adjustment policy: if an item you bought at Costco goes on sale at Costco within 30 days of your purchase, you can get the difference refunded — no return, no rebuy.

Example: you buy a TV for $899, and two weeks later Costco marks it down to $749. You're owed the $150 difference, because the drop happened inside your 30-day window. That's not a price match (matching a competitor); it's Costco refunding its own markdown. The full policy — US vs. Canada, exclusions, how to claim — is in our complete price adjustment guide.

Price match vs. price adjustment — the difference that matters

These two terms get used interchangeably, but they're not the same:

	Price match	Price adjustment
What it does	Matches a competitor's lower price	Refunds a Costco price drop
Does Costco offer it?	No	Yes
Time limit	—	30 days from purchase
What you do	(n/a)	Keep the item, claim the difference

So when people ask "does Costco price match?" the useful answer is: not competitors — but yes, it adjusts its own prices for 30 days. If you were hoping to bring in an Amazon price, that won't work. If you want money back because Costco dropped the price, that absolutely does.

How to claim a Costco price adjustment

1. Confirm the item dropped in price at Costco and that you're within 30 days of purchase.
2. Check it isn't excluded — seasonal and clearance items often don't qualify.
3. Claim it: in-warehouse at the membership counter with your receipt/membership, or through the online price adjustment form for Costco.com orders.
4. Get the difference refunded to your original payment method.

In Canada the 30-day window applies too, with a slightly different process — see Costco price adjustment Canada.

The catch: you have to notice the drop

Costco won't tell you when a price falls. If you don't spot the markdown and claim it before day 30, the money's gone — which is why most eligible adjustments go unclaimed. A receipt-based Costco price tracker like CostRefund watches your purchases daily and alerts you the moment an eligible item drops, with a countdown to your deadline. Scan a receipt once, and it handles the watching for you.
