Costco will refund the difference if the price drops within 30 days of your purchase

If you buy something at Costco and the price goes down within 30 days, you can return to the warehouse with your receipt and get the difference back. Costco calls this their price adjustment policy. You do not need to return the item itself — just show your receipt and the current lower price, and a cashier will refund the difference to your original payment method.

This applies to almost everything Costco sells: electronics, clothing, furniture, groceries, and household goods. The main exceptions are items marked as "final sale" or "as-is," which are already discounted and cannot be adjusted further. Costco also does not adjust prices on items that were on sale when you bought them, only on regular-priced items that later drop.

The 30-day window starts from the date on your receipt. If 31 days have passed, Costco will not process the adjustment, even if the price has fallen significantly. This is why it helps to check prices on items you buy regularly — electronics and seasonal goods drop most often.

How to request a price adjustment at the warehouse

Go to the customer service desk at any Costco location with your receipt. Tell the associate you would like a price adjustment because the item you purchased has dropped in price. They will ask to see your receipt and will look up the current price in the system or ask you to show them the item on the shelf.

The process usually takes a few minutes. The cashier will process the refund to the card or payment method you used originally. If you paid with a credit or debit card, the refund appears as a credit on your account within a few business days. If you paid with a Costco Cash card, the balance is added back when ready.

You do not need to bring the item with you, but it helps if you can point out where it is in the warehouse so the associate can confirm the new price. If the item is no longer in stock or has been removed from shelves, the associate can still look up the price in the system using the product code from your receipt.

What items are not may be able to access for price adjustments

Costco does not adjust prices on clearance items, final sale merchandise, or anything marked as "as-is." These items are already reduced and are sold with the understanding that the price will not change. You can usually spot these items by a red tag or a note on the shelf label.

Items that were already on sale or discounted when you bought them also cannot be adjusted lower. For example, if you purchased something during a promotion and the regular price drops later, you cannot request an adjustment. The policy only covers items that were at regular price when you bought them.

Costco also does not adjust prices on items purchased online through Costco.com. Online purchases have their own return and refund process, which is separate from the warehouse price adjustment policy. If you bought something online and the price dropped, you would need to return the item and repurchase it at the new price, or contact Costco's online customer service.

The 30-day window and how to track it

The 30 days are counted from the date printed on your receipt, not from when you opened the item or brought it home. If you bought something on January 1st, you have until January 31st to request the adjustment. On February 1st, the item is no longer may be able to access, even if the price dropped that same day.

Keep your receipt in a safe place if you think a price might drop. Costco receipts are printed on thermal paper that can fade over time, so storing it in a cool, dry place helps preserve it. If your receipt becomes illegible, bring your Costco membership card and the item to customer service — they can look up the transaction using your membership number, though this takes longer.

For items you buy regularly, it can help to check the price every few weeks during the 30-day window. Electronics and seasonal items (like holiday decorations, summer furniture, or winter clothing) tend to drop most often. Groceries and household staples usually hold their price longer.

What happens if you bought the item with a gift card or Costco Cash

If you paid with a Costco Cash card or a Costco gift card, the refund is added back to that card when ready. You can use the extra balance on your next purchase. If you paid with a physical gift card that is no longer active or has been lost, the refund cannot be processed — this is why keeping your receipt is important.

If someone else gave you a Costco gift card and you used it to buy something that later dropped in price, you can still request the adjustment. The refund goes back onto the same gift card, even if you no longer have it in your possession. You will need your receipt to prove the original purchase.

Price adjustments versus returns: which option is better

If an item drops in price, you have two choices: request a price adjustment or return the item and buy it again at the new price. For most situations, a price adjustment is faster and easier — you just go to customer service with your receipt and leave with the refund in minutes.

A return requires you to bring the item back, possibly in its original packaging, and then repurchase it. This takes more time and effort. However, if the item is damaged, defective, or you have changed your mind about keeping it, a return might make more sense than an adjustment.

Costco's return policy is separate from price adjustments. You can return most items within 90 days for a full refund, regardless of price changes. If you are outside the 30-day price adjustment window but still within 90 days, returning and repurchasing is your only option to get the lower price.

Frequently Asked Questions

Can I request a price adjustment if I do not have my receipt?

You can try using your Costco membership card — an associate can look up the transaction by your membership number. However, this takes longer and may not work if the purchase was made a long time ago or at a different warehouse. Keeping your receipt is the fastest way to process an adjustment.

What if the price dropped more than 30 days ago but I just noticed?

Costco's policy is firm on the 30-day window. Once 30 days have passed from your receipt date, you are no longer may be able to access for a price adjustment, even if the price dropped significantly. Your only option at that point is to return the item if it is still within the 90-day return window and repurchase it at the new price.

Do I have to go to the same warehouse where I made the purchase?

No, you can go to any Costco warehouse. Bring your receipt and show a cashier at customer service. The system is shared across all warehouses, so they can process the adjustment regardless of which location you visited originally.

Can I request a price adjustment on items I bought online?

No, Costco's price adjustment policy only applies to warehouse purchases. Online orders have a different process. If you bought something on Costco.com and the price dropped, contact Costco's online customer service to discuss your options, which may include returning and repurchasing the item.

What if the price dropped and then went back up?

You can still request the adjustment as long as you are within 30 days of your purchase and the price is currently lower than what you paid. The adjustment is based on the current price at the time you request it, not the lowest price it reached during those 30 days.
