Voltage Coffee Supply review for KeepCart: Stop Coupon Leaks
Jan. 27, 2026
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!
