Scam. Avoid. Uninstall.
When you access a product through an affiliate link, Honey will replace the website's affiliate cookies with their own, effectively stealing the affiliate fee from the influencers who brought you to the website in the first place.
They also seem not to show the best coupon deals on purpose when a website pays them to do so. Avoid at any cost, uninstall if you have it.
There's currently a lawsuit by the youtuber Legal Eagle about this.
