KeepCart was an incredibly easy way for us to stop bleeding margin on orders. We noticed that coupon extensions were just giving every shopper 25% off codes that we didn't even know had leaked, and in a couple of minutes we were able to stop them with keepcart and it's been a very high ROl for us.

Great experience here over the last couple of months. We had a lot of coupon codes all over the net that weren't cleaned up from influencer, affiliate programs, and other seasonal promotions. Was hard to just get a handle on what was going on. This was my first stop, automatically documenting in one place what codes are even being used, was a hugely useful utility for us. From there, we were able to go through the highest value and most active codes and work our way down until we cleaned everything up. Literally thousands of dollars in incremental contribution margin every month now that our house is cleaned up. Ongoing retention features and other modules are awesome additions that keep driving additional value month after month. I don't know how you could run a DTC brand and not have KeepCart watching your back.

We run a Danish fitness brand with a high AOV, where we rely heavily on structured campaigns, launches, and controlled discount strategies. Before KeepCart, we didn’t have a clear overview of how and where our codes were being shared, which made it difficult to protect margins without limiting our marketing efforts.

KeepCart gave us a much clearer picture and control layer without disrupting our existing setup. Instead of guessing, we can now confidently scale campaigns knowing our discounts are being used as intended.

The setup was fast, and it’s been a smooth, no-friction addition to our stack that simply does its job in the background.

KeepCart has been a very valuable tool for our Shopify store. It helps us prevent discount codes from being leaked, protects our margins, and gives us much better control over how our coupons are distributed. Before implementing it, we had several affiliate codes appearing on third-party coupon websites, which led to incorrect attribution and unnecessary margin loss. The app has helped us clean up that issue and manage our promotions in a much more controlled and professional way.

KeepCart has been a great addition to our Shopify store. It has helped us identify and block leaked discount codes, giving us much better control over our promotions and protecting our margins.

The setup was straightforward, and the dashboard makes it easy to monitor blocked codes, leaks, and duplicate discounts. We also appreciate that the app runs in the background without affecting our store’s performance.

The KeepCart team has been very proactive and attentive, consistently reaching out with recommendations and helping us get the most value from the platform.

If you use discount codes and want to prevent unauthorized coupon sharing while protecting revenue, KeepCart is definitely worth considering. Highly recommended.

KeepCart has been a great tool for us to leverage. With no alternative to prevent discount code scraping, monitor discount codes being used by unintended customers, etc. it’s been great to have an added layer of security. No hassle at all, just a quick and easy 5-10 minute setup guided by the KeepCart team as needed and you’ll be well on your way to making improvements to your tech stack.

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.

Easy to use, well-developed, and we've had a responsive team. This is one of those apps that just works, which is what we need.
