KeepCart: Stop Coupon Leaks

We run a fitness brand (Shogun Sports) with a high AOV, and coupon leaks were quietly eating into our margins without us fully realizing it. We thought we had a solid affiliate program, but KeepCart revealed that a significant chunk of "affiliate commissions" we were paying out were actually from leaked coupons being used by random shoppers, not real affiliates driving traffic.

Since installing, we've blocked the abuse and our bottom line has improved noticeably. Revenue hasn't dropped, if anything, we now know which commissions are legitimate and which weren't. For stores with high AOV or an active affiliate/discount strategy, this app essentially pays for itself.

KeepCart has been a great addition to our stack. It helped us quickly detect coupon leaks and prevent unwanted discounts, especially from browser extensions, directly improving our margins. Simple to use and genuinely effective.

We were losing more revenue to coupon abuse than we realized. KeepCart made it super easy to lock that down, and setup took maybe 10 minutes. It just runs quietly in the background doing its job. We've already seen the payoff. Honestly wish we'd installed it sooner.

We set up KeepCart after discovering continual discount code abuse, primarily originating from couponing/referral sites. The onboarding process couldn't have been easier (took maybe 10 minutes total).

It's been a game-changer in recognizing old codes that were still being used by customers and shutting those respective discounts down.

We're very happy with it so far and will continue to use it in the future to preserve margins.

We’ve had a great experience using KeepCart. It has been a key tool for us in protecting our checkout from unintended discounts and coupon misuse, especially from extensions and affiliate-related leaks.

Before using KeepCart, we didn’t have clear visibility into how and where our discount codes were being shared. Now we have much better control and insight, and we’ve been able to reduce unnecessary discounting while keeping our campaigns structured and intentional.

The app runs smoothly, is easy to manage, and the impact on our bottom line was noticeable quite quickly. On top of that, their team has been responsive and helpful whenever we’ve needed support.

If you’re serious about safeguarding your margins and getting full transparency around your coupon performance, KeepCart is absolutely worth having in your tech stack. Highly recommended.

Great app — solved our coupon code leak issues almost instantly.

Setup was quick, and it works seamlessly without affecting site performance. We now have full control over discounts and clear visibility into how codes are used.

It’s already paid for itself by preventing unnecessary discounting. Support is also fast and helpful.

Highly recommend

We run Planet Mujo, a pain relief brand where margins matter, and KeepCart has instantly become one of the most important apps on our Shopify store.

Our main reason for installing it was to stop coupon extensions like Honey and Capital One Shopping from scraping and auto-applying discount codes we never intended to be public. KeepCart blocks these extensions perfectly. Before this app, we were constantly fighting margin leakage from leaked codes, unauthorized discounts, and customers stacking promos. Now, problem solved.

Setup took only a few minutes, and everything worked right out of the box. No theme conflicts, no site slowdown, no complicated configurations. Their support team is also excellent, fast responses and incredibly helpful. If you're tired of coupon extensions eating into your margins, KeepCart is the fix. Simple, effective, and absolutely worth it.

Highly recommended by the Planet Mujo team.

Great app that's really helping improve our margins. Coupon code leaks are such a pain and require a lot of manual effort to combat - normally. KeepCart has automated the process, reducing the amount of excess discounts we give out improving our profitability. The analytics it provides on usage really boosts confidence in it working well. Great app that is as simple as turning on and making more money, providing an excellent ROI on the app.

Great tool to help keep tabs on discount codes being used, see if anything has been leaked, and generally monitor discounts. The app dashboard is also very clear and easy to understand.

We were able to quickly spot coupon codes that had leaked to extensions and deal sites and shut them down before they caused more damage. It gave us visibility we didn’t have before and made it much easier to protect our checkout and margins. Simple to use and genuinely useful.
