Several big retailers refund the difference if their own price drops after you buy: Target within 14 days, Costco within 30 days, Best Buy within its return window (15 days for most products for most customers), and Home Depot typically within 30 days. Walmart doesn't offer price adjustments. Bring your receipt and ask at customer service, or contact the store for online orders.

How to claim a price adjustment
- Find the new lower price for the identical item at the same store (or its website, if the policy allows).
- Check you're inside the window and that the item isn't excluded, such as clearance or a limited-time event.
- Bring your receipt (or order number) to customer service, or use chat or phone for online orders.
- Get the difference refunded to your original payment method.
How to never miss a price drop
- Set a reminder for the last day of the window on bigger purchases.
- Use price-drop alerts on items you bought or buy often.
- Keep receipts in the store app or photograph them.
- Buy early during sales season at stores with adjustments. If the price drops, claim it. See Black Friday price matching.
- Scan the barcode of the item on the shelf with Price Match Paradise. No account needed to start.
- Review matching offers across supported retailer sources, with stock status and price-match guidance when the retailer data is available.
- Decide in the aisle: ask for a match, buy it here because it's already the best price, or pick it up where it's cheaper.
What about "return and rebuy"?
If a store won't adjust but you're still within the return window, some shoppers return the item and buy it again at the lower price. It can work, but stores can refuse, and it's not an option for opened or final-sale items. Check the store's return policy first.
