KeepCart: Stop Coupon Leaks

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 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.

If for no other reason than being able to track codes out in the wild / leaked and get updates on those, you should consider this app. It's a great tool to fight back against all of the code injection sites, especially if you work with influencers, etc and want better directional data on actual code efficacy there.

Extremely helpful insights into how our customers are finding and using discount codes.

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.

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.

KeepCart has been great in helping us monitor and prevent code leaks. It’s already identified several incidents early on, and we’re exploring code blocking to take our protection even further. The team’s responsiveness and support have made implementation seamless and efficient.

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.

If you are tired of seeing your profit margins eroded by coupon extensions like Honey, Capital One Shopping, and Rakuten, KeepCart is an absolute game-changer.

Before installing this app, we struggled with discount codes—intended only for specific influencers or email segments—leaking onto the web and being auto-applied at checkout. KeepCart solved this immediately. It effectively blocks over 150 different coupon extensions and even alerts us if a code has been leaked to a third-party site so we can take action.

The dashboard is incredibly clean and provides great insights into how many 'leaks' are being prevented in real-time. It’s also been fantastic for stopping affiliate and reseller abuse by preventing duplicate account fraud.

The setup was quick and easy. If you’re serious about protecting your brand’s value and keeping your margins intact, this app is a must-have!

Loving this! Being able to keep our offers exclusive helps to keep my community engaged and loyal. Game changer!
