A price adjustment is a change to the original selling price of a product or service after the sale is made. In everyday retail use, it means this: you bought something, the price dropped shortly after, and you can get the difference refunded. The term also covers rebates and, in commercial contracts, formula-driven price changes tied to an index. This article focuses on the retail version, because that’s what most people are trying to do when they look this up.
Price Matching and Price Protection Are Not the Same
Retailers use “price adjustment” loosely, and mixing up the two policies is what usually wastes people’s time at the customer service desk.
Price matching happens before or at checkout. You’ve found an identical item cheaper at a competing store and you’re asking the retailer in front of you to honor that lower price. The item has to be the same brand, model, size, and color. Most retailers publish a list of competitors they will match and exclude third-party marketplace sellers, auction sites, and limited-quantity doorbuster deals.
Price protection, which is also called a price adjustment or price guarantee, applies after you’ve already bought. If the same retailer drops the price within a set window, you can ask for a refund of the difference. This is the policy most searches are really about.
How Long You Have to Ask
The window varies by retailer, and the details are worth checking before you assume you’re out of time.
- Target allows requests within 14 days of purchase.1Target. Target Price Match Guarantee
- Costco gives online shoppers 30 days.2Costco. Price Adjustment – Costco.com Orders
- Best Buy generally ties its adjustment window to its return period, which is 15 days for most products and extends to 60 days for paid membership holders.
Fourteen to 30 days is the range you’ll see most often at major retailers. Always confirm the current policy with the specific store, since these change.
How to Request a Retail Price Adjustment
The process is simpler than most people make it. You need two things: proof you bought the item and proof the price dropped.
- Proof of purchase: your original receipt, email order confirmation, or packing slip. Digital receipts work at most retailers.
- Proof of the lower price: for a price match, a current advertisement, a live link to the competitor’s product page, or a screenshot. For post-purchase price protection at the same retailer, the store can verify the current price on its own.
Where you submit depends on how you bought the item. Online orders usually go through the retailer’s chat, a dedicated phone line, or a web form. In-store purchases usually mean a trip to the customer service desk with your receipt. Target allows price adjustments right at the register for items purchased within its 14-day window.1Target.

The retailer will confirm the item is truly identical and that the lower price isn’t excluded by policy. Common exclusions: clearance prices, limited-time flash sales, prices from third-party sellers on marketplaces like Amazon, and prices that require a competing store’s membership or loyalty program. If the claim is approved, the refund goes back to your original payment method.
When the Refund Posts
Credit card refunds typically appear within five to 14 business days after the retailer processes them. Timing inside your billing cycle matters. A refund processed right after your statement closing date won’t show on that statement even though it will hit your current balance sooner.3Experian. How Do Credit Card Refunds Work Debit card refunds follow a similar timeline. Cash refunds at a physical register are immediate.
Keep copies of what you submitted: the claim, receipt, screenshots of the lower price, and any reference number the retailer gives you. If nothing has posted after two weeks, that documentation is what settles the follow-up call.
Sales Tax on the Refund
When the price of the item drops, the sales tax you paid on it should drop too. If you paid $100 plus $8 in tax and the price falls to $80, you’re owed $20 plus $1.60 in excess tax. Most retailers handle this automatically as part of the adjustment. If you get the price difference back but not the tax, you can ask for the tax portion separately. Refund claim rules vary by jurisdiction, so if the retailer won’t cooperate, your state’s department of revenue is the next step.
Rebates Are a Different Kind of Price Adjustment
Rebates lower what you ultimately pay, but the timing and effort depend on which kind you’re dealing with.
An instant rebate is applied at checkout. The lower price is what you pay, and there’s nothing further to do.
A mail-in rebate works the other way. You pay full price upfront and then submit a claim form with proof of purchase, usually the receipt and UPC barcode, to the manufacturer. Processing typically takes six to ten weeks before a check or prepaid card arrives. That delay is part of the design. Manufacturers count on a share of buyers never completing the submission, which is why the advertised “after rebate” price can look aggressive.
If a rebate offer states a fulfillment timeframe, the company is expected to meet it. The FTC has taken enforcement action against companies that failed to deliver on time, establishing in consent orders that rebates must be provided within the time specified, or within 30 days if no time is given.4Federal Trade Commission.

One thing people miss: rebate checks expire. If you don’t cash yours in time, the funds eventually fall under your state’s unclaimed property laws. Dormancy periods before escheatment typically range from three to five years, but by that point the check itself has long since voided, and you’ll need to file a claim with your state’s unclaimed property office to recover the money.
Credit Card Price Protection
Several major credit card issuers used to offer automatic price protection as a cardholder benefit, with Citi’s “Price Rewind” the best-known version. Citi discontinued that benefit in September 2019, and most other major issuers have similarly pulled back. If you’re expecting your card to handle price drops for you, read your current agreement first, because this benefit has become rare.
The Contract Meaning of Price Adjustment
Outside of retail, “price adjustment” also refers to a clause in a long-term commercial contract that changes the price over time based on an outside index. These escalation clauses protect sellers from being locked into a fixed price while costs rise, and protect buyers from arbitrary increases by tying the change to something objective.
The two most common indexes are the Consumer Price Index (CPI) and the Producer Price Index (PPI), both from the U.S. Bureau of Labor Statistics. CPI is widely used in rental agreements, insurance policies, and support payment contracts.6U.S. Bureau of Labor Statistics.

The formula is usually straightforward: take the index value at the adjustment date, subtract the value at the contract’s start or last adjustment, divide by the starting value, and multiply by 100. That percentage is applied to the base price. Many contracts add a cap that limits how much the price can rise in any single period, and sometimes a floor that guarantees a minimum adjustment regardless of index movement.6U.S. Bureau of Labor Statistics.
