How do I spot a fake coupon or discount code website?
Fake coupon sites harvest your email and personal data, install browser extensions that track your shopping, or charge for 'membership' to access codes that do not work.

Explanation
Discount-hunting is extremely common, and fraudsters have built an entire ecosystem of fake coupon websites to exploit it. Some are straightforward data collectors: you must register with your email, name, and sometimes phone number to access a code that is either expired, invalid, or identical to codes freely available elsewhere. Your data is then sold.
A second category installs browser extensions that claim to automatically apply coupons. Some legitimate extensions do this (Honey, Capital One Shopping), but malicious lookalikes collect your browsing history, shopping behaviour, and sometimes intercept forms to harvest typed data. The extension name is similar to a trusted one but is from an unverified developer.
A third model is the paid membership scam: you pay a monthly fee to access an exclusive members-only discount club. The codes provided are either widely available for free or do not work at checkout. These subscriptions are difficult to cancel and often buried in confusing terms.
For browser extensions, only install from developers with a long, verifiable history and a large user base. Check the permissions requested — a coupon extension needs to see shopping sites but does not need access to your entire browsing history or the ability to read content on every page you visit.
Common red flags
- Registration required for codes that are normally publicly available
- Browser extension requests unusually broad permissions
- Paid membership required to access discount codes
- Code site is not associated with the retailer being discounted
- Codes consistently expire immediately or do not work at checkout
- Site uses alarming checkout messages like 'your items are about to sell out'
What to do now
- Use coupon codes only from the retailer's own website or well-known, established platforms
- Audit your browser extensions and remove any you do not recognise or no longer use
- Unsubscribe from any coupon membership before the next billing cycle
- If you shared personal details, monitor for spam and phishing targeted at you
- Report fake extension clones to the browser's extension store
Frequently asked questions
Is the Honey browser extension safe?
Honey (now owned by PayPal) is a well-known, legitimate coupon extension. Exercise caution with lesser-known extensions that mimic its interface or promise similar functionality from an unverified developer.
How do I safely find discount codes?
Check the retailer's own website, their email newsletter sign-up, and established platforms with a long track record. Many retailers offer first-order discounts through their own checkout flow.
Can a browser extension steal my passwords?
A malicious extension with permission to read page content can log keystrokes including passwords on any site. Only install extensions from verified developers with a transparent privacy policy.
