Price Adjustment Refunds: Which Stores Still Pay You Back After a Price Drop?

By Rowan Keller·Published October 27, 2026

Has been buying open-box and returned stock for over a decade, and built Warehouse Watcher to stop losing track of it.

A price adjustment refund is the difference between what you paid and the lower price the same store charges shortly after your purchase, and at the right stores it takes a single request to get it back. Costco refunds its own price drops for a full 30 days, Target does it for 14 days, and Best Buy matches its own lower price at any point inside its return window. Walmart and Amazon mostly refuse, which is why where you buy a big-ticket item matters almost as much as when you buy it.

The money is real. Retailers do not advertise these policies at the till, and most shoppers never ask, so the refund sits unclaimed. Set a reminder for a week after any purchase over $100, check the price once, and claim what is yours if it dropped.

Costco: 30 days, and the most generous price adjustment refund in retail

Costco's rule is the cleanest in the business: if an item you bought drops in price at Costco within 30 days of purchase, Costco refunds the difference. No competitor ad, no haggling, no returning the item and rebuying it. The policy covers both warehouse and Costco.com purchases, and it applies to the big stuff people actually worry about: TVs, appliances, furniture, laptops.

Two limits matter. First, Costco only adjusts its own prices. If Best Buy undercuts Costco on the same TV, that is not Costco's problem. Second, the channels do not cross: a warehouse purchase is adjusted against warehouse prices at the Returns counter of the warehouse where you bought it, and a Costco.com order is adjusted online through the price adjustment request in your order history. Online credits typically land in 5 to 10 business days.

You do not even need the receipt. Your purchases are tied to your membership, so staff can pull up the transaction from your card. If you are buying a TV at Costco, our Costco TV buying guide covers the models worth watching, and this 30-day window is the reason a slightly early purchase there is low-risk.

Target: 14 days, and only Target's own prices now

Target quietly ended competitor price matching in July 2025, closing a policy shoppers had used for years to match Amazon and Walmart. What survives is a narrower but still useful rule: if the price of something you bought drops at Target, on Target.com, in the Target app or at your local store, within 14 days of purchase, you can request the difference back.

Ask at Guest Services in store or through Target.com customer service, with your receipt or order number and the current lower price pulled up live on your phone. Target excludes clearance, closeout and liquidation pricing from adjustments, so a red clearance sticker does not trigger a refund. Fourteen days is the shortest window on this list, so check prices the weekend after a Target run, not the month after.

Best Buy: matches rivals and its own price drops

Best Buy runs the broadest policy of the big US electronics retailers. Its Price Match Guarantee covers a published list of qualified competitors, including Amazon, Walmart, Target and Costco, as long as the item is new, identical (same model and colour), and in stock at that competitor right now. Third-party marketplace sellers do not count, and neither do membership-only prices like a Prime-exclusive deal.

For a price adjustment refund after your own purchase, the rule is just as friendly: if Best Buy lowers its in-store, online or app price while you are still inside the return and exchange period, ask and they will refund the difference. Show the lower price on your phone in store, or open a chat on BestBuy.com with the link ready. Know the exclusions before you rely on it: clearance and open-box items are out, and Best Buy suspends price matching from the Thursday before Thanksgiving through the Monday after, so do holiday matching before or after that weekend.

Walmart and Amazon: where the refund stops

Walmart.com does not price match at all: not competitors, not its own stores, and not a lower price on something you already bought online. The one lever is in physical stores, where Walmart will match the Walmart.com price on an identical item, and the manager on duty has the final say. That is a checkout tool, not a post-purchase refund, so with Walmart the price has to be right on the day.

Amazon is stricter still. There is no post-purchase price adjustment, and customer service cannot refund the difference when an item drops the day after delivery. Your only real lever is the standard return window: return the item and buy it again at the lower price. On a $40 gadget that is not worth the tape and the trip; on a $900 TV it absolutely is. The smarter play is checking the price before you buy. WarehouseWatcher tracks open-box stock, regular sales and lightning deals across seven countries, so scan the US deals or Canada deals feed before a big Amazon order, and use our guide to the best deals on Amazon for the timing patterns.

The exact script for a price adjustment refund

The wording matters less than having the facts in hand: your receipt or order number, the date you bought it, and the current lower price visible on your phone or in the store's own system. Then ask for the policy by name. Naming it signals you know it exists, which ends most resistance before it starts.

• In store: "Hi, I bought this on [date] for [$X]. It's now priced at [$Y], and I'm inside the price adjustment window. Could you refund the difference to my original payment method?"
• On chat or phone: "I'd like to request a price adjustment on order [number]. I paid [$X] on [date], and the item is currently listed at [$Y] on your site."
• If the first answer is no and you are inside the stated window, ask once, politely: "Could a supervisor check that? My understanding is the policy covers own-price drops within [14/30] days."
• If the store genuinely has no policy, as with Amazon, stop arguing and run the return-and-rebuy math instead.

One habit ties it together: keep a single phone note with the item, store, price paid and the date the window closes. Thirty seconds to write it, and it turns price drops from bad luck into a routine rebate.
