If you’ve searched for “Membercost.com review” or “Is Membercost.com a scam?”, you’re not alone. Many people are being targeted by websites claiming you can earn big rewards — like a $750 Costco gift card — just for signing up and completing simple offers. But is Membercost.com real… or too good to be true? In this review, we break down the facts so you can make an informed decision.

What Membercost.com Claims
Membercost.com presents itself as a platform where users can supposedly:
- Join a “Costco review program”
- Complete a few easy tasks or deals
- Earn rewards like gift cards or cash
On the surface, the site may look professional. It uses familiar branding and promises high payouts to attract visitors. However, several scam‑alert websites and security tools indicate this is not a legitimate rewards program.
Key Reasons Membercost.com Is Considered a Scam
No Official Costco Partnership
Membercost.com is not endorsed or affiliated with Costco or any verified rewards or review program. Legitimate reward programs from big companies like Costco are usually promoted directly on their official websites or through well‑known survey and reward platforms, not third‑party domains.
Low Trust and Safety Scores
Independent scam‑detection tools give Membercost.com very low trust scores, suggesting it may be unsafe:
- Scam Detector gave the site a low rating (around 20 out of 100), labeling it suspicious, unsafe, and doubtful.
- ScamAdviser reports a very low trust score, noting hidden ownership details, a young domain, and registrar associations with other risky sites.
- Other safety check services classify the site as potentially unsafe or risky.
These kinds of signals often show a site may be used for phishing, spam, or data harvesting.
Redirection Through Affiliate Offers
Investigations show that sites like Membercost.com can redirect users through a chain of third‑party offers and deals that are paid to the scam operators — not actually connected to Costco rewards. Users are told to complete “deals” such as downloading apps, signing up for free trials, or entering personal data, but no real payout is delivered at the end.
Unrealistic Reward Promises
The central offer — a $750 Costco gift card for minimal effort — is highly unrealistic. Legitimate survey and reward sites do offer gift cards and small payments, but they clearly state terms, reward limits, and payout proofs. Membercost.com shows no evidence of actual verified payouts.
Potential Safety Risks
Here are common risks associated with interacting with Membercost.com:
- You may be asked for personal data like email and phone number
- You could be redirected to unsafe or malicious sites
- Some offers involve hidden free trials that auto‑subscribe you
- You may receive spam emails or texts afterward
These are hallmarks of sites designed more to profit from your data and affiliate clicks than to reward you.
How the Scam Typically Works
While the exact flow may vary, this is a common structure:
- An ad or link promises easy cash or gift card rewards.
- You are sent to Membercost.com’s landing page.
- The site claims you’ll get rewards if you complete a few steps.
- You’re directed to multiple “offers” or surveys from other networks.
- You never receive the promised gift card or payout.
This model focuses on generating affiliate revenue for the scam hosts, not giving rewards to participants.
What to Do If You’ve Interacted With the Site
If you’ve already visited the site or entered some information:
- Stop interacting with the offer immediately. Do not complete further deals.
- Avoid entering sensitive payment information.
- Monitor your inbox for spam or suspicious messages.
- If you signed up for a “free trial,” locate their email and cancel it right away.
Always check promotions directly at official brand sites — in this case, Costco’s official site (https://www.costco.com) — rather than unfamiliar third‑party domains.
How to Spot Similar Scams in the Future
Here are some general tips to avoid scams like Membercost.com:
- Be cautious if an offer sounds too good to be true.
- Check reviews on reputable sites like Scam Detector or ScamAdviser before engaging.
- Avoid entering personal or payment information on unknown sites.
- Look for clear contact info, privacy policies, and legitimate business details.
Final Verdict
After reviewing security data and scam tracer reports, Membercost.com does not appear to be a legitimate or safe way to earn Costco gift cards or cash rewards. The low trust scores, lack of official affiliation, and red flags around redirects and data collection all point toward it being a suspicious or potentially scam website.
If your goal is to earn rewards or gift cards online, use well‑known survey platforms and make sure offers come from official brand channels.
