Reply from Coupert Science LLC

Hi there,

We’re sorry for the frustration and appreciate you sharing your feedback.

Regarding coupons, Coupert helps collect and test available coupon codes from merchants and partner sources, but the actual validity, expiration time, usage limits, and applicable products are all controlled by the merchant side. Because of this, some stores or orders may occasionally not have an available working coupon at a certain time, which we understand can be disappointing.

If you experienced issues with a specific merchant or coupon, please feel free to contact us at [tphelp@coupert.com](mailto:tphelp@coupert.com) with the merchant/store name and any screenshots or details. Our team can help manually review and verify the situation for you.

As for the login requirement, signing into a Coupert account is necessary because features such as cashback tracking, reward balances, withdrawals, and personalized cashback/coupon services need to be securely connected to a specific account. This helps ensure your rewards and cashback are tracked correctly and protected properly.

We’re continuously working to improve the overall user experience and make the login process as simple and convenient as possible.

Thank you again for your feedback and support.
