How Costco's online-only deals work
Costco.com only
Costco’s terms: “Online-only promotions valid only for purchases on Costco.com.”
Limits per member
Most offers carry a limit, 2 for computers and 5 to 10 for most others, shown with each offer above.
Online and warehouse prices differ
Costco notes that “Pricing on Costco.com may be higher than Costco warehouse pricing”, so a warehouse price on the same item can be lower than the online one.
One day
Every Cyber Monday offer is valid on November 30 only, so an order has to be placed that day.
Already bought it? Get the difference
If something you bought from Costco in the 30 days before November 30 is cheaper on Cyber Monday, Costco's price adjustment policy lets you ask for the difference.

When is Costco Cyber Monday 2026?+
Monday, November 30, 2026. Costco's Cyber Monday offers are valid that one day only, on Costco.com.
Are Costco Cyber Monday deals in the warehouse?+
No. Every Cyber Monday offer is marked Online Only, and Costco's terms say online-only promotions are valid only for purchases on Costco.com. Black Friday weekend offers, which also run through November 30, include many that are in warehouses as well as online.
What are the best Costco Cyber Monday deals?+
Costco lists 10 offers for 2026. The biggest dollar savings are $100 to $600 off PC laptops and desktops (search “PCDeals26HM” on Costco.com), $500 off a Whirlpool 24" dishwasher, $1,000 off a 2-carat diamond platinum ring and $2,000 off diamond halo earrings. There's also a Hisense CanvasTV with a 3-year Allstate plan from $899.99 and two $50 Applebee's gift cards for $74.99.
Is Costco Cyber Monday different from Black Friday?+
Yes. Black Friday offers run Friday, November 27 through Monday, November 30, many of them in warehouses as well as online. Cyber Monday is a separate, shorter list that is online only and valid on November 30 alone.
Can I get a price adjustment if something I bought is cheaper on Cyber Monday?+
Often, yes. Costco refunds the difference when something you bought drops in price within 30 days, and Costco.com orders are claimed with its online price adjustment form. Costco treats online and warehouse prices separately and decides final eligibility.
Bought something before the sale?
CostRefund checks what you bought at Costco against today's prices and tells you when you're owed a refund.
