It is a scam. It overwrites affiliate links, while coupon codes are managed by partnering shops.

Absolutely disgusting practices. They fool the consumer into believing they're getting the best deal, but they work with businesses to limit their coupon database. They also override commissions, screwing over the influencers who promote them. Do not install.

Scams you, the store, and the affiliates at the same time

Borderline malware. Replaces referral links with their own at the last moment on checkout, even if you're purchasing through someone else's referral link. They often don't list a deal so that they can push the line that you're already getting the best deal, then they get a cut through their referral, when deals do in fact exist and are easy to find. Never install this extension.

Honey only shows store approved coupons (usually 5-10%) which are rarely the best deals. In addition they get their money from taking commission on your purchases, stealing money from anyone who actually refers you to a product, and they do this regardless of whether or not they provided you with a coupon or not.
You're better off hunting for coupon codes the old fashioned way to get the best deals, even if it takes longer.

This is a scam addon that changes affiliate tracking links to steal from online creators, even when it doesn't find any coupon codes to apply. It also does not find you the best deal, Honey purposely finds worse deals for you on products by companies that partner with them.

Absolute scam, documented to steal from consumers and creators.

It's a scam, they are ripping off your favorite creators that you are trying to support by clicking a link that will earn them a commission. When Honey pops up at checkout, and say they have coupons for you, and you click on it to check for coupons, it replaces the cookie of your favorite creator with their own stealing the commission. And you probably don't even get a coupon code.

Scam, doesn't work and they overwritte the affiliated cookies so they get money with every purchase you make.

Honey is the largest scam addon/extension that has ever existed. They steal money from affiliate links to pocket the money that otherwise would've gone to the content creators.
