Understanding Costco's price adjustment policy can save you hundreds of dollars every year. Whether you're a regular Costco shopper or just made a big purchase, knowing the official rules, time limits, and potential restrictions can help you maximize your savings. Here's everything you need to know about the Costco price adjustment policy.
What Is the Official Costco Price Adjustment Policy?
Costco's official price adjustment policy states that if an item you purchased drops in price within 30 days, you can request a refund for the difference. This policy applies to both warehouse purchases and items bought on Costco.com.
The key point to understand: Costco will only adjust prices for their own price reductions. They do not price match with competitors like Amazon, Walmart, Target, or any other retailer. The price adjustment only applies when Costco itself marks down an item you recently purchased.
How the Policy Works
When you buy something at Costco and the price drops within 30 days, you're entitled to get back the difference. The process is straightforward because all your purchases are automatically tracked through your Costco membership card.
You don't need to save receipts or remember exactly what you paid. Costco's system maintains a complete purchase history linked to your membership number, making it easy for both you and Costco staff to verify your transactions and confirm price changes.
What Qualifies for a Price Adjustment?
Almost everything sold at Costco qualifies for price adjustment, with a few important exceptions. Here's what you can get adjusted:
- Electronics – TVs, laptops, tablets, cameras, and other tech devices
- Major appliances – Refrigerators, washers, dryers, dishwashers
- Furniture – Sofas, beds, office furniture, outdoor furniture
- Groceries – Food items, beverages, pantry staples
- Household goods – Cleaning supplies, paper products, toiletries
- Clothing and accessories – Apparel, shoes, jewelry
- Seasonal items – Holiday decorations, outdoor equipment
- Health and beauty – Vitamins, skincare, personal care products
The policy covers both regular-priced items and sale items. If you bought something on sale and it drops even further within 30 days, you can still get the additional difference back.
What Doesn't Qualify: Important Exceptions
There are specific categories that Costco explicitly excludes from price adjustments:
1. Gold Bullion and Silver Coins
Precious metals are excluded from the price adjustment policy due to their high market volatility. Gold and silver prices can fluctuate significantly within minutes, making it impractical for Costco to offer price adjustments on these items.
2. Special Event Purchases
Items purchased immediately before major sales events like Black Friday, Cyber Monday, or Costco's special warehouse sales may not qualify for price adjustments. Costco reserves the right to exclude these purchases to prevent gaming of the system.
3. Reseller Accounts
If you're a verified reseller or business buying inventory for resale purposes, you're not eligible for price adjustments. This policy is designed to benefit regular members making personal purchases.
4. Cross-Channel Price Differences
Costco.com and warehouse locations operate with separate pricing structures. You cannot request a price adjustment on a warehouse purchase based on Costco.com pricing, or vice versa. Each channel's price adjustments only apply to prices within that same channel.
Time Limits and the 30-Day Window
Understanding the timing is critical to successfully claiming a price adjustment. Here are the key time-related rules:
When the Clock Starts
The 30-day window begins on the date of purchase, not the delivery date. For online orders, this means the day you placed and paid for the order, not when it arrived at your door. For warehouse purchases, it's the date shown on your receipt.
When You Must Request the Adjustment
You must submit your price adjustment request within 30 calendar days from your purchase date. After day 30, Costco will not honor the price adjustment, even if the price dropped on day 29.
Multiple Price Drops
If an item drops in price multiple times within your 30-day window, you can request adjustments for each drop. There's no limit to the number of adjustments you can request on a single item, as long as each drop occurs within the 30-day period.

How Costco Tracks Purchases Via Membership
One of Costco's biggest advantages is their integrated membership tracking system. Every purchase you make—whether in-store or online—is automatically linked to your membership number.
Automatic Purchase History
When you swipe your membership card at checkout or log in to Costco.com, your purchase details are recorded:
- Item purchased and quantity
- Purchase date and time
- Price paid
- Payment method used
- Store location (for warehouse purchases)
Benefits of Membership Tracking
This system offers several advantages for price adjustments:
- No receipt needed – Staff can pull up your entire purchase history instantly
- Faster processing – No need to manually verify purchase details
- Accuracy – Eliminates errors from lost or damaged receipts
- Convenience – You can request adjustments even if you forgot the exact purchase date
Privacy and Data Use
Costco uses your purchase data solely for operational purposes like processing returns, price adjustments, and improving inventory management. Your data is protected under Costco's privacy policy and is not sold to third parties.
When Costco Can Deny Your Request
While Costco's price adjustment policy is generally customer-friendly, there are situations where they may deny your request:
1. Outside the 30-Day Window
This is the most common reason for denial. If you request an adjustment on day 31 or later, Costco will not process it. The 30-day limit is strictly enforced.
2. Prohibited Item Categories
As mentioned earlier, gold bullion, silver coins, and certain other specialty items are excluded from the policy.
3. Suspected Abuse or Fraud
If Costco detects patterns that suggest you're abusing the policy—such as repeatedly buying and returning items to exploit price fluctuations—they may deny your requests and potentially revoke your membership.
4. Business or Reseller Accounts
Verified business accounts purchasing for resale are not eligible for personal price adjustments.
5. Price Errors or System Glitches
If a price drop was due to a clear pricing error (like a $1,000 TV mistakenly marked at $100), Costco may refuse to honor the adjustment. These situations are rare but can occur.
6. Items Purchased During Exclusion Periods
Items bought immediately before major sales events may fall under exclusion periods. Costco communicates these restrictions during checkout or in their terms.
What to Do If Your Request Is Denied
If Costco denies your price adjustment request, you still have an option: return the item and repurchase it at the lower price. Costco's generous return policy allows you to return almost anything for a full refund, even without the original packaging. You can then buy the same item again at the new, lower price.
The Challenge: Manual Price Tracking Is Time-Consuming
While Costco's price adjustment policy is generous, it comes with a major catch: Costco will not notify you when prices drop. It's entirely up to you to:
- Remember every item you purchased and when
- Check Costco regularly to see if prices have changed
- Compare current prices against what you paid
- Submit your adjustment request before the 30-day window closes
For frequent Costco shoppers who buy dozens of items per month, this becomes an impossible task. You could easily miss a $50 price drop on a TV, $30 on a vacuum cleaner, or $20 on a set of kitchen knives simply because you didn't check back in time.
