    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.

    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.

    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.

    Game changer! We have a fairly large influencer program and have seen an unusal spike in discounts lately due to promo codes. While that's to be expected, there was no way to know all the places the codes lived. Now with KeepCart we can easily tell whose code needs to be updated, all the places the codes are leaked, do we need to block them, etc. The details on this app are incredible. The platform is user friendly and I can tell everything I need to know as soon as I log on. It's a must-have tool for your business!

    This is a great tool to use! Has helped stop multiple 40% discount codes from being leaked which has saved our business! We recommend it for anyone running discount codes.

    Shortly after we started providing discount codes to a particular set of new customers, we saw many non-qualified customers using that discount code. We then started to search for a plugin that would help mitigate this issue. We compared two plugins and decided that KeepCart was the best option for our situation. So far, we are very happy with how well it handles the discount codes! We like using the protected link option the best for our customers. All the information flows through to our orders the way we like, we can track the analytics of our discount code, and see all the usage of our first misused code. Thanks for saving us from a huge headache!!

    We were losing too much margin from affiliate codes leaking to coupon websites. This app is ever improving to help stores like ours keep our revenue sources untainted. Thank you!

    If you do affiliate marketing like shareasale, PMX, avantlink, etc. and you don't use a product like KeepCart, then you are wasting your time. We found out that one of our top affiliates was just uploading his coupon codes into Honey so we were paying, Honey, The Affiliate, and giving the customer a discount on top of everything else. KeepCart helps us block sites like Honey and with their Coupon Leaker tracker, we can see what coupons are being used outside of platforms like meta and tiktok. Pro move: Don't delete coupon codes that are leaked, just move them down to 2% or 3% off, you will be surprised how many people still check out with a coupon for 2% off.

    We implemented KeepCart recently with the initial goal of tracking code leaks, and it has been a fantastic tool so far! It has already helped us flag multiple leaked codes, and we're excited to expand our usage of KeepCart with automated code blocking.
