Costco will refund the difference if the price drops within 30 days of your purchase
If you buy something at Costco and the price drops within 30 days, you can return to the warehouse with your receipt and get the difference back in cash or as a credit to your membership card. This applies to most items in the warehouse, though some categories have different rules. You do not need to return the item itself — Costco will calculate the difference and hand you the money on the spot.
The 30-day window is firm. If 31 days have passed since you bought the item, Costco will not refund the price difference, even if the drop happened on day 32. The clock starts from the date on your receipt, not from when you noticed the price change.
Key Takeaways
- Costco refunds price differences for most warehouse items if the price drops within 30 days of purchase, with no item return required.
- You must bring your original receipt to the warehouse to request the refund; the refund is processed at the membership desk or customer service counter.
- Electronics, jewelry, and items marked as final sale are excluded from price-drop refunds.
- The 30-day window is measured from the date on your receipt, and Costco will not honor requests after that period ends.
- Online purchases through Costco.com have a separate 30-day price-match policy that works differently than warehouse purchases.
What items are excluded from price-drop refunds
Costco does not refund price differences on electronics, which includes televisions, computers, cameras, and major appliances. These items are final sale once you leave the warehouse. Jewelry and watches are also excluded, as are items specifically marked as final sale on the shelf tag or receipt.
Gasoline, medications, and items sold at the Costco food court are not may be able to access for price-drop refunds either. If you are unsure whether a specific item qualifies, ask at the membership desk before you leave the warehouse — they can tell you whether that product category is covered.
How to request a price-drop refund at the warehouse
Bring your original receipt and go to the membership desk or customer service counter. Tell the staff member the item you bought and the current price you saw. They will look up the price you paid on your receipt, compare it to today's price, and calculate the difference. If the price has indeed dropped and the item is not excluded, they will hand you cash or credit the amount to your membership account on the spot.
You do not need to bring the item with you, and you do not need to have the item in your possession. The refund is based entirely on the receipt and the current shelf price. The whole process usually takes a few minutes.
Price drops on Costco.com work differently than warehouse purchases
If you ordered something from Costco.com and the price dropped, the refund process is not the same as the warehouse. Costco.com has a 30-day price-match policy, but you must request it through your online account or by calling Costco customer service at 1-800-955-2292. You cannot walk into a warehouse and request a refund for an online purchase.
For online orders, log into your account, find the order, and look for a price-match or price-adjustment option. If you do not see one, call the number above and provide your order number. Costco will review the price history and issue a refund to your original payment method if the price has dropped within 30 days. This can take several business days to process, unlike the immediate refund at the warehouse.
Timing matters: the 30-day clock and how it works
The 30 days are counted from the date printed on your receipt, not from the date you noticed the price drop. If you bought something on January 1st and the price dropped on January 15th, you have until January 31st to request the refund. On February 1st, you are outside the window and Costco will decline.
Costco does not track price changes for you or send notifications when items drop. You have to notice the price change yourself and bring your receipt to the desk within the 30-day period. Keep your receipt if you think there is any chance you might want to return an item or check on a price drop.
What to do if Costco refuses your price-drop request
If a staff member tells you the item is not may be able to access or that you are outside the 30-day window, ask to speak to a manager. Managers have more authority to make exceptions, especially if the price drop happened very close to day 30 or if there is confusion about the receipt date. Be polite and have your receipt ready to show them.
If the manager still refuses and you believe the refund should have been granted, you can contact Costco's corporate customer service at 1-800-955-2292. Explain the situation and provide your receipt number and membership number. They cannot reverse a decision made at the warehouse, but they can note the complaint in your account and may offer a one-time exception if this is your first request.
Price-drop refunds versus Costco's return policy
The price-drop refund is separate from Costco's general return policy. You can return most items within 90 days for a full refund, even if the price has not changed. If you want to return an item and also get a price-drop refund, you only get one or the other — you cannot stack them. In most cases, returning the item for a full refund is the better choice if you are outside the 30-day price-drop window.
If you are within 30 days and the price has dropped, the price-drop refund is faster because you do not have to return the item. If you are past 30 days but within 90 days, you can still return the item for a full refund, but you will not get the price-drop difference.
Frequently Asked Questions
Do I have to return the item to get a price-drop refund?
No. Costco will refund the price difference based on your receipt and the current shelf price. You do not need to bring the item back or prove you still have it. This is one of the main reasons the price-drop refund is faster than a full return.
Can I get a price-drop refund if I paid with a credit card instead of cash?
Yes. Costco will refund the difference in whatever form you prefer — cash, credit to your membership account, or a credit back to your original payment method. Ask the staff member which option works best for you.
What if the price dropped but then went back up before I noticed?
Costco refunds based on the current price at the time you request the refund, not the lowest price the item ever reached. If the price is back up, there is no refund to give. You have to catch the price drop while it is still in effect.
Does the 30-day price-drop policy apply to Costco Business locations?
Yes, Costco Business warehouses honor the same 30-day price-drop refund policy as regular Costco locations. Bring your receipt to the business membership desk and follow the same process.
Can I price-match Costco against other stores?
No. Costco does not price-match against competitors. The price-drop refund only applies if Costco itself lowered the price. If Target or Walmart has a lower price, Costco will not match it.
