At checkout, the extension can apply eligible coupons, helping users save without searching manually.

The service supports shopping across thousands of popular websites and is available as an extension for Chrome, Safari, Firefox, and Edge, as well as an app on Google Play and the App Store. Coupert also offers store deals, a coupon submission feature, a rewards program, and a missed coupon guarantee. The company says its tools are free to use and highlights a max-savings guarantee. Coupert earns revenue through affiliate programs, which may provide commissions when users purchase through its links.
