Costco Holiday and Black Friday Price Adjustments: How the 30-Day Rule Works in November and December
By Ankur Khurana, founder of ShelfVerse · Last updated November 10, 2026
Quick answer. Costco's price match policy covers items that drop in price within 30 days of purchase. For items with sale dates (Costco names Holiday Savings Promotions as an example), you must ask within both the promotion's dates and the 30 days. Requests made after the promotion ends may be denied. So if something you bought in October or early November goes on a holiday sale, ask while the sale is still running.

This guide summarizes Costco's published rules and, where marked, widely reported but unofficial shopper experience. Costco can change its policy or decline a request at its discretion; check with Costco before you rely on it.
The holiday season is when Costco prices move the most, and when a lot of members buy early. That makes it the best time of year for the 30-day price adjustment, and the easiest to miss because of one extra rule about promotion dates. Here is how to line the two clocks up.
For members other than resellers, purchases that reduce in price within 30 days of the purchase date are eligible.
For items with specific sale dates (Holiday Savings Promotions is Costco's example), the request must be submitted within both the active promotional dates and 30 days of the purchase date. Costco says requests after the promotion ended may be denied.
Online orders: use the Request a Price Match form on Costco.com. Costco says credits are typically issued within 5 to 10 business days to the original form of payment.
Warehouse purchases: ask at the returns counter of the warehouse where you bought the item.
Costco does not match other retailers' prices, does not match warehouse prices for Costco.com purchases, and can deny any request at its sole discretion.
The page doesn't mention Black Friday by name. Treat a Black Friday price as a sale price on a dated promotion, which is the case Costco describes. For the full rules see the complete price adjustment guide.
The two clocks: 30 days and the sale dates
A holiday price adjustment needs two things to be true when you ask: you're within 30 days of buying, and the promotion is still active. Whichever clock runs out first ends your window. Examples with made-up dates:
You bought
Sale runs
Last day to ask
Oct. 20
Nov. 16 – Nov. 30
Nov. 19 (day 30 comes first)
Nov. 5
Nov. 16 – Nov. 30
Nov. 30 (the sale ends before day 30)
Nov. 20
Nov. 27 – Nov. 30
Nov. 30 (the sale ends first)
Dec. 2
Ended Nov. 30
Nothing to claim; the sale price wasn't available in your window
The third row is the one people miss: a short Black Friday sale can close well before your 30 days do. If you see a lower price on something you bought recently, go that week.
A holiday-season checklist
Keep every receipt. Early gift shopping means many purchases to track. Warehouse receipts show the date, item number and price paid.
Watch the sale dates, not just the price. Costco's Holiday Savings page lists validity dates per item and tags items as warehouse, online or both. A warehouse-only deal doesn't help an online order, and the reverse. See the online price adjustment guide.
Check the shelf tag. A newly marked-down tag is the usual trigger. Our price tag codes guide covers what shoppers report about the endings (unofficial).
Group your claims. One visit with several items beats several trips. Make sure each item qualifies on its own.
Do it in the right place. Warehouse purchase, warehouse counter. Online purchase, online form.
Mind closures. Costco's 2026 holiday page says warehouses are closed Thursday, Nov. 26, 2026 for Thanksgiving. Hours on other days vary by warehouse, so check yours before you drive over.
Returns during the holidays
If you'd rather return than adjust, Costco's return policy page describes a satisfaction guarantee with limitations, and a 90-day window (from the date you received it) for televisions, projectors, major appliances, computers, tablets, smart wearables, cameras, drones, camcorders, MP3 players and cellular phones. That page doesn't state a holiday extension, so don't assume one. Precious metals, shop cards and gift cards are among the items it lists as non-refundable.
Returning and rebuying at the new price is a different route from a price adjustment, and the policy doesn't promise either outcome in a given situation. A price adjustment is usually less hassle when you want to keep the item.
What not to count on
Claims after the promotion ends. Costco says these may be denied.
Beating other stores. Costco doesn't match other retailers.
Quantity limits. Many holiday deals carry per-member limits, and adjustments only apply up to the limit. More in our exclusions guide.
Unofficial rules. You'll read that staff always approve or always refuse in certain cases. Costco's page says it decides at its sole discretion.
Make it automatic
The hard part isn't the policy, it's remembering which of your purchases are still inside 30 days when a sale starts. ShelfVerse (free, independent, not affiliated with Costco) tracks your purchases from account sync or receipt photos, alerts you when one drops, shows the days left, and gives you the wording for the membership desk. You can also browse recorded prices on the Costco price history pages and this week's price drops.

I bought before Black Friday and the price dropped. Can I get the difference?Possibly.
