Costco giveaways that show up in your social feed are almost always fake — and the honest answer to “is it legit?” depends entirely on who is actually running the offer. Costco Wholesale Corporation is a real, publicly traded company. But Costco itself has publicly stated it is not handing out cash cards to Facebook users, and the company maintains a “Currently Known Scams” page on its customer service site precisely because impersonators keep abusing its name.
So the split is simple. The retailer is legitimate. Many of the viral posts using its logo are not. Most of what circulates as “Costco giveaways” on Facebook, Instagram, TikTok, and in text messages comes from third parties with no relationship to the warehouse chain — people running affiliate funnels, phishing pages, or hidden subscription sign-ups.
There is a narrow band of real promotions worth knowing about: brand sweepstakes run by Costco’s suppliers, which are legal, published, and free to enter. This guide walks through who runs what, how the money works, what shoppers report, and how to tell the genuine article from an imposter in about five minutes.
Who Actually Runs Costco Giveaways
Three very different groups put the Costco name on prize offers, and they are not equally trustworthy.
The first is Costco Wholesale itself. The company communicates through costco.com, its member emails, and its verified social accounts. When it has addressed viral prize posts, it has done so bluntly — stating that it is not giving away Costco Cash Cards to Facebook users and is not associated with those programs.
The second group is legitimate suppliers. Brands that sell inside the warehouses — supplement makers, food companies, personal care brands — regularly run sweepstakes tied to a Costco purchase or a Costco-themed post. These are hosted on the brand’s own website, carry full official rules, and name the brand as sponsor, not Costco.
The third group is imposters. They have no connection to anyone and simply borrow the logo.
How Costco Makes Money — And Why That Matters
Understanding Costco’s business model tells you a lot about which offers make sense. Costco’s profit engine is membership fees, not advertising. In fiscal 2025, membership fee revenue rose 10% to $5.323 billion, according to the company’s Form 10-K filed with the SEC. It reported 81 million total paid memberships and 914 warehouses worldwide as of August 31, 2025.
Membership pricing is public. Effective September 1, 2024, the U.S. Gold Star fee rose to $65 a year and the Executive Membership to $130, with the Executive 2% Reward annual cap raised to $1,250.
That model explains something important. A company earning billions in recurring fees from members it already has does not need to buy engagement by promising strangers $1,000 cards for a like and a share. The economics of viral “free money” posts point away from the real retailer, not toward it.
Supplier sweepstakes, by contrast, make obvious business sense. A brand pays for a prize because it wants shelf attention. That is why those promotions are real — and why they always carry a sponsor’s name.
What Shoppers and Winners Publicly Report
Public reporting on the imposter versions is extensive and consistent. Newsweek documented a Facebook scheme built around free Christmas food boxes attributed to Costco. Snopes has fact-checked a widely shared “anniversary” coupon offer. Infosecurity Magazine reported that Costco published screenshots of more than a dozen fraudulent emails, texts, and posts impersonating the company.
The pattern people describe is remarkably uniform. A post or text says you have been “specially selected.” A short survey follows. Then a prize — a laptop, a phone, a cooler, a cash card — is offered for a small shipping charge, often around ten dollars.
What shoppers report next is the tell. The card gets charged, the prize never arrives, and in many accounts a recurring subscription appears on the statement, disclosed only in fine print on the checkout page.
Federal data backs up the scale. The FTC reported that consumers lost $2.1 billion to scams that started on social media in 2025, with nearly 30% of all scam-loss reports originating there. Shopping scams — sites impersonating well-known brands — were the most reported type, and people reported losing more money to scams starting on Facebook than on any other platform.
How Imposters Abuse the Costco Name
Imposter operations follow a repeatable playbook. They create a page using the Costco logo, sometimes posing as an executive or an employee, and post about an anniversary, a store closing, or a surplus of inventory.

They build credibility first. The account shares ordinary-looking photos and deals for weeks, collecting followers, before the fake prize post goes up. Comments and shares are required to “enter,” which pushes the post into more feeds.
The link then leads off-platform to a page that mimics costco.com. From there the goal is one of three things: harvest personal data, capture card numbers, or enroll you in a negative-option billing program.
This conduct is squarely illegal. The FTC’s Impersonation of Government and Businesses Rule took effect April 1, 2024, prohibiting impersonation of businesses in commerce and giving the agency authority to seek consumer redress and civil penalties. None of this reflects on Costco Wholesale, which is the brand being victimized alongside shoppers.
Real vs. Fake Costco Giveaways: The Signs
Here is the practical comparison for evaluating any offer using this name.
| Genuine promotion | Imposter offer |
| Hosted on costco.com or a named supplier’s own domain | Hosted on a lookalike domain or a link shortener |
| Full official rules: sponsor name, entry dates, prize value, odds statement | No rules page, or a rules link that goes nowhere |
| States “No purchase necessary” | Asks for shipping, processing, or verification fees |
| Never requests card, bank, or Social Security numbers to enter | Requests payment details or sensitive personal data |
| Posted by a verified account with a long, consistent history | New page, few posts, mismatched handle spelling |
| Realistic prize count — a few winners | “Everyone who shares wins” or thousands of cash cards |
Two FTC rules of thumb settle most cases. You should never have to pay to claim a prize, and only scammers ask to be paid in gift cards. Any offer that trips either one is not worth another minute.
Verify Costco Giveaways in Five Minutes
You can resolve almost any of these on your own, quickly.
- Open a new browser tab and type costco.com by hand. Never use the link in the post. If the promotion is real and Costco-run, it will be findable there.
- Search Costco’s customer service site for its “Currently Known Scams” page and check whether your offer is already listed.
- Look for the official rules. A legitimate sweepstakes names its sponsor, the entry window, prize value, and eligibility. No rules, no entry.
- Check the account itself. Click the profile name, confirm the verification badge, and scroll the post history. Pages created recently are a strong signal.
- Read the domain carefully, character by character. Imposter sites rely on small misspellings and extra words in the address.
- If money or card details are requested, stop. Report the post to the platform and file a report at ReportFraud.ftc.gov.
Costco giveaways that survive all six checks are usually supplier sweepstakes — free to enter, clearly sponsored, modest in prize count. Those are worth your time. The rest, the ones promising cash cards for a share, are the ones the company has already told the public it has nothing to do with.
Frequently Asked Questions
Does Costco run giveaways on Facebook?
Costco has publicly stated it is not giving away Costco Cash Cards to Facebook users and is not associated with those programs. Any post promising cash cards to everyone who likes or shares should be treated as an imposter offer, not a Costco promotion.
Are any Costco giveaways real?
Yes — but usually the sponsor is a brand sold inside the warehouses, not Costco Wholesale. These supplier sweepstakes are hosted on the brand’s own site with published official rules, and they state that no purchase is necessary to enter or win.
Why do fake Costco giveaways ask for a small shipping fee?
The small fee captures your card number and, in many reported cases, starts a recurring charge disclosed only in fine print. The FTC’s guidance is direct: you should never have to pay anything to claim a legitimate prize.
What should I do if I already entered a fake giveaway?
Contact your card issuer or bank about the charge and any recurring billing, change passwords you reused on the fake page, and report the post to the platform. You can also file a report at ReportFraud.ftc.gov, which feeds the FTC’s enforcement database.
