Coupert tests and applies promo codes at checkout when you’re online shopping. After you install the extension (or mobile app), Coupert runs seamlessly in the background while you browse supported online stores. At checkout, it will test and apply coupons and discount codes and apply the one(s) that save you the most money (while also saving you time in the process). If a store supports cashback, Coupert will also notify you of the money you’re eligible to receive.^{[2]

It’s actually pretty straightforward—when a purchase is made through Coupert, they earn a commission from the store for driving sales (the purchases are tracked through an affiliate network). This is why Coupert can offer their services for free to users, without having to sell your data.^{[4]

Why isn’t Coupert working for me?

Coupon codes are not always available. Coupert is great at finding coupons and promo codes from all corners of the Internet, but there’s no guarantee that the store, brand, or product you’re shopping for has any coupons online. If this is the case, Coupert won’t be able to apply any discounts.
- What if Coupert misses a coupon? You’re not out of luck—if no savings are applied on eligible orders or a valid coupon is missed, users may receive a cash reward as part of Coupert’s Max-Savings Guarantee (terms apply).
2
Coupert may not work on websites for niche or very small retailers. Coupert searches more than 200,000 sites and brands for coupons, discounts, vouchers, and special offers. That’s a lot of websites, but not all of them. If you’re on a niche or small and independent store’s site, there’s a chance that Coupert may not be able to find coupons for it.
- Some websites may also have restrictions on coupon stacking. In these cases, Coupert may only be able to apply one discount instead of all available.
Coupert generally works with pop-up ad blockers, but sometimes, these can interfere with purchase verification. Enable Coupert Guard (Coupert’s own integrated blocker) for the best experience, and whitelist Coupert in your ad blocker settings (or temporarily turn off your ad blockers) to ensure cashback tracking and coupon functionality work properly.

Browser extensions can be glitchy sometimes. It’s just a fact of using the Internet. Permissions settings, extension or browser updates you haven’t installed yet, and even the number of extensions you have running at one time might affect Coupert or other extensions’ performance.
- For the best experience, keep your browser and extensions updated.
- Missing the Coupert button? Double-check your extensions toolbar and make sure it’s installed. You may have to enable it, toggle it “on,” or pin the extension icon to your toolbar to see it.^{[7]
