Costco price adjustment policy
Costco price adjustments: ask for the difference within 30 days
If Costco lowers its own price within 30 days of your purchase, you can ask for the difference while the lower price is still running.
Within 30 days of purchaseA price adjustment is a store policy, not a consumer right. Costco sets the window and the exclusions, and Costco decides each request. Here is what its policy says and how to ask.
How to ask Costco for the difference.
- 01
Check both dates. Costco's page says a request "must be submitted within both the active promotional dates and 30 days of the purchase date."
- 02
Warehouse purchase: go to the Returns counter at the warehouse where you bought the item.
- 03
Costco.com order: open the order and choose "Request a Price Match" on the order page. Costco credits the difference to your original payment method in about 5 to 10 business days.
- 04
Costco decides. It may decline a request at its discretion.
What to bring
- Your receipt or your Costco.com order, which show the purchase date and the price you paid.
- The lower Costco price from the same place you bought: the warehouse price for a warehouse purchase, the Costco.com price for an online order.
- For a warehouse purchase, a trip to the warehouse where you bought it.
What doesn’t qualify
- Lower prices at other retailers. Costco adjusts only to its own price.
- A Costco.com price on a warehouse purchase, or a warehouse price on a Costco.com order. Online and warehouse prices are not matched to each other.
- Precious metals.
- Requests made after the promotion ends or more than 30 days after purchase.
- Costco may also decline a request at its discretion.
It watches the Costco price while the window is open.
- 1. You add your Costco receipt. A photo, a screenshot, or the details typed in. You confirm which items to watch; nothing is tracked from a guess.
- 2. It watches the price for Costco's window. It checks automatically for as long as the window is open: within 30 days of purchase. You do nothing.
- 3. It tells you when a drop shows up. In the app and by email, with the price you paid, the lower price, and the deadline.
- 4. You ask Costco. Receipt Weasel does not file the claim or contact Costco. Costco decides.

Costco price adjustment questions.
- Does Costco do price adjustments?
- Yes, to its own lower price. If Costco's price drops within 30 days of your purchase and the lower price is still running, you can ask for the difference. Costco may decline at its discretion.
- Does Costco match other stores' prices?
- No. Costco's price adjustment covers only Costco's own lower price.
- Can I get the Costco.com price on something I bought in the warehouse?
- No. Costco does not match online and warehouse prices to each other, so compare against the price where you bought.
- How long does a Costco.com price adjustment take?
- You request it with "Request a Price Match" on the order page, and Costco credits the difference to your original payment method in about 5 to 10 business days.
