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.

I’ve been using Coupon Hacker for several months now, and its ability to automatically search and apply coupon codes at checkout has consistently yielded savings I never would have found on my own. It’s like having a professional bargain hunter built right into my browser, and it has saved me significant money on everything from electronics to fashion to groceries online.

Handy app and very clean

been looking for something like this for a while

Does it Work For Roblox Robux Codes?

love it....

I was using this extension with shop and it automatically placed the order when running the codes. It placed a non refundable order without permission.

The extension behaves unobtrusively and only shows up at checkout. nice to see it working behind the scenes.

I run a small online store and tested it, it handled the checkout fine and found a discount we were running internally. good tech.

Handy and practical. I'd like better European language support, but the results have been solid so far.

Perfect for last minute deals. it applied a promo at checkout just as I was about to pay ended up saving about 30%

Simple install, solid result. it's become my default coupon searcher for indie shops and brand pages that other tools skips.

love the idea, thank developer.

Does it work on Ebay?!

good work, recommended

I have been looking for one that isn't to complicated and THIS is perfect

not working

Does not work. Constantly restarts.

Installation was effortless, the extension respected my privacy settings. got a $15 save on my first try.

Found a vip style code for a brand site that other extension never found. that saved me money than i expected.

The AI feature seems legit it pulled codes from a subreddit thread and one of them worked. nice work by the devs.

As someone who shops internationally, I saw it work on a few European stores. had to refresh once, but overall solid.

short and sweet, it finds codes that actually work. use it with ad-block off for best results.

saved 40% on a jacket that was an awesome surprise. simple UI and no weird permissions. thumbs up.

very handle while holiday shopping. tested multiple codes in the background and picked the best. would like faster runs on very large carts though.

I'm a bargain hunter and this tools is surprisingly good on smaller retailers.it found a code that cut the price by nearly a third.

save me serious money on a sneaker drop found a code other extension missed and applied it without me lifting a finger. super easy.

Used the extension a couple of times and got always a bigger discount with it when compared to Honey and Coupert. This is now my go to for now. It seems it works on smaller sites the best.

"Could not detect price" First thing it said the moment I tried it. Most likely due to it being sellauth.com which isn't necessarily a much used site. Do find it kind of strange how it wasn't able to detect the price when it was taking up a 20th of the screen. Haven't used it on other websites, but from what I can see, it looks like a great extension.

Really cool extension. Got a 50% discount on my $400 order lol. Also use Honey and others but this extension was able to find the best deal for me. After emailing the developer it seems there are several new features that will be released soon that will make it faster. Can't wait!

Great idea, just painfully slow. Have you considered after first run to sniff out what network request was made to apply the coupon code ? That way you can hit the API directly and in parallel for all subsequent ones.

I've used this successfully before, but latest update shows "Waiting for page to load completely" on every checkout page

Does not seem to work currently, on all pages it just shows "Waiting for page to load completely". Updating browser, disabling ad-blockers, refreshing, etc all do not seem to fix the issue.

Waiting for page to load completely...

AMAZING!

"No coupon field detected."

Coupon Hacker is the real deal. The AI actually tests dozens of codes in the background and finds stuff that no other extension has picked up. I use it every time I shop. Highly recommend for frequent online buyers.

It doesn’t always find a code, but when it does, it’s usually a good one. I especially like how it finds “VIP” or member-only deals without me having to sign up for anything. Would love to see more support for European sites though.

I was skeptical at first, but this extension is seriously amazing. I was shopping on Nike and Coupon Hacker found a hidden 25% off code that wasn’t even on Honey or RetailMeNot. It works fast and feels smarter than other coupon tools I’ve tried.

Really cool idea but tried this on a shop.app checkout and although it did go through a set of applicable coupons it didn't register them correctly so in the end it said the best coupons were worth $0 off and they were in the wrong order for best one. Really cool just not working for me
