If something you bought at Costco drops in price within 30 days of your purchase date, Costco refunds you the difference. For Costco.com orders you request it online with the Request a Price Match button, and the credit goes back to your original payment method, usually in 5 to 10 business days. For warehouse purchases, you take it to the Returns counter at the store where you bought it. There’s no form to hunt for and no receipt-in-a-shoebox requirement.
| Best for | Anyone who bought something over roughly $150 at Costco in the last month |
| Expected benefit | The full price difference. Worthwhile on big-ticket items, rarely worth it under about $50 |
| Time required | A few minutes online, or one stop at the Returns counter |
| Upfront cost | $0. Costco membership required, as with any Costco purchase |
| Main catch | On a dated promotion you must be inside both the promo window and the 30 days. The promo window usually closes first |

Costco calls it a “price match,” which is confusing, because it is not competitor price matching. That’s the single biggest misunderstanding about this policy, and it gets its own section below.
How long do you have to ask?
Costco’s wording: “purchases that reduce in price within 30 days of the date of purchase are eligible for a price match.”
Two details inside that sentence do the work:
- The clock runs from the date of purchase, not the delivery date. On a slow-shipping item, you can burn a week of your window before the box arrives.
- For items on a dated promotion, Costco requires the request to land “within both the active promotional dates and 30 days of the purchase date.” Both conditions, not either. If the sale ends on day 12, day 13 is too late even though you’re well inside 30 days.
That second rule is the one that quietly costs people money, and it’s the reason to file the request the day you notice the drop rather than “sometime this month.”
What the 30-day window actually looks like
The rule is easier to see on a timeline than in a sentence. Here is an illustrative example using the policy as written. The numbers are made up to show the mechanics, not a purchase we made.
| Day | What happens | Can you still claim? |
|---|---|---|
| Day 0 | You buy a patio set online for $699. It ships in a week | Nothing to claim yet |
| Day 7 | It arrives. Note the clock started on day 0, not today | Yes, 23 days left |
| Day 15 | It drops to $549 in a promotion running days 12 to 19 | Yes. Inside 30 days and inside the promo. Claim $150 |
| Day 21 | You finally get around to it. The promo ended on day 19 | No. Still inside 30 days, but the promo window closed |
Day 21 is the whole lesson. Nine days of the 30 were still on the clock and the money was gone anyway, because the promotional window is the shorter of the two deadlines. Whenever the drop is a dated sale rather than a permanent markdown, treat the sale’s end date as your real deadline.
Does Costco price match other stores?
No. Despite the name, this policy only covers Costco’s own price drops. Costco does not match prices from other retailers, and it does not match its own warehouse prices against Costco.com purchases.
That last part surprises people: warehouse and online are treated as separate channels. Costco’s stated reason is that Costco.com prices account for shipping and handling that warehouse prices don’t. Finding the same item cheaper in-store than you paid online is not a qualifying price drop.
How do you actually request it?
| Where you bought it | What to do | How you’re refunded |
|---|---|---|
| Costco.com | Select the Request a Price Match button and complete the form | Credit to your original form of payment, typically 5 to 10 business days |
| In a warehouse | Inquire at the Returns counter at the location where you made the purchase | Handled at the counter |
Note the warehouse wording carefully: Costco specifies the location where you made the purchase. If you bought it on a trip and you’re now closer to a different warehouse, call ahead before you drive.
What’s excluded?
Costco names precious metals outright: they “are not eligible for a price match.” Gold bullion is called out separately as ineligible for price adjustments or promotions. Given how those prices move, that exclusion is unsurprising and absolute.
Items with promotional quantity limits are eligible only up to that limit. And Special Order Kiosk and Home Improvement installed products run on their own rules, tied to the signed contract date and the pre-tax price rather than a simple 30-day window. If you’re mid-project on a countertop or a set of windows, ask before you sign rather than assuming the standard policy applies.
Who this isn’t worth it for
This policy is genuinely useful, but it isn’t universal. Skip it if:
- The item was cheap. On a $9 pack of paper towels the difference won’t cover the trip. The rough floor is around $50, and the policy really earns its keep above $150.
- You bought it more than 30 days ago. There’s no goodwill extension written into the policy. Past the window, the answer is no.
- You’re comparing against another retailer. A lower price at Target or Amazon is not a qualifying drop, however annoying that is.
- You’re a reseller. Costco’s wording limits the 30-day eligibility to “members other than resellers.”
- You bought precious metals. Explicitly excluded, with no discretion at the counter.
Is it worth the effort?
On the things Costco is actually known for, yes: the $400 mattress, the $1,200 television, the patio set that goes on sale three weeks after you carried it out.
The habit that catches those is small. When you buy anything at Costco over roughly $150, put a reminder in your phone for three weeks out to check the current price. Three weeks keeps you inside the 30-day window with room to file. It takes ten seconds at checkout.
The short version
- 30 days from purchase date, not delivery date.
- On a dated promo you need to be inside both the promo window and the 30 days.
- It’s not competitor matching, and warehouse prices don’t count against online orders.
- Online: Request a Price Match, then 5 to 10 business days. Warehouse: the Returns counter where you bought it.
- Precious metals are out. Installed products follow separate contract rules.
