A site built entirely on fake…
A site built entirely on fake engagement and clickbait. It constantly asks you to download things but never provides any discount codes.

We're sorry to hear that your experience was disappointing. Coupert does not require users to download additional software to access coupon codes beyond our supported browser extension or app. Please note that coupon codes are provided by merchants or our partners, and it's normal for some codes to expire or have specific usage restrictions, which may prevent them from working in certain situations. If you believe there's an issue with a particular merchant or coupon, please contact us at [email protected] with the merchant name and any relevant screenshots. We'll be happy to investigate and improve the experience where possible.

We’re truly sorry to hear that you're experiencing issues with your keyboard while using our extension. We understand how frustrating this must be, especially when it interferes with your typing. This kind of issue can sometimes occur due to conflicts with other browser extensions or settings. We recommend disabling other extensions temporarily to see if that resolves the problem. Please reach out to our team at [email protected] for further assistance, and we'll be happy to help you troubleshoot this issue. Thank you for your understanding!

Time waster, not very helpful.
Coupert often offers many potential coupon and discount codes and churns thru them. After testing them which can take a bit of time, it nearly always ends up saying, "You have got the best price". I don't find it very helpful and somewhat distracting.
