I can't put into words how atrocious this extension is. I was trying to figure out for hours why I keep getting redirected to amazon.co.uk from all other Amazons even when I deleted my cookies and session or when I switched to a VPN with many location attempts. Finding and disabling this despicable extension finally fixed it. Removed and reported for abuse. WHY. WHY?!

I’ve tried many coupon tools before, but Coupon Hacker actually finds codes that work. It automatically tested multiple coupons at checkout and applied the best one without me doing anything. I ended up saving more than I expected, and the whole process felt seamless and effortless.

Instead of opening dozens of tabs searching for promo codes, this extension does everything for me in seconds. The AI-powered coupon discovery really makes a difference — it finds VIP and hidden codes that other extensions never seem to catch.

I’ve tried many coupon tools in the past, and most of them either spam you with popups or rarely find valid codes. Coupon Hacker is different. It quietly runs in the background and only steps in when there’s an opportunity to save money. I’ve already saved a noticeable amount across several purchases, especially with VIP or hidden coupons I didn’t even know existed.

Randomly removed items from my list and started scrolling all over the place. Really weird behavior from an extension. Don't trust it.

Automatically placed an order while running codes. Do not use this extension with the shop app.

The Coupon worked and I saved some money!

Easy to install, easy to use, and super powerful. recommend it.

Installation was quick and straightforward, and I didn’t need to adjust any complicated settings. The extension works exactly as described and finds valid promo codes during checkout. Very happy with the overall experience.

Honestly, this app is a game-changer! It saves me the endless hunt for coupons and finds the best deals in seconds. I saved a ton on my last order

This extension genuinely surprised me. I’ve used many coupon tools before, but Coupon Hacker consistently finds discounts that others miss. The automatic testing of hidden and VIP codes feels smart and efficient, and it saves me both time and money. I no longer waste time searching random coupon sites because this does it better in seconds.

Great! Already saved me a few bucks.
