When I briefly used this extension, I noticed it basically never worked in actually providing me codes (and I sometimes *could* do better just by Googling). It's now been exposed that this isn't just an ineffective piece of software, but a key part of their marketing strategy: suppressing codes which are known to work so as to benefit their corporate partners. This is contrary to the extension's description, enough so that it reasonably constitutes false advertising.

In addition, the extension has been shown to override affiliate cookies on sites which it works on. This acts to deceive customers, and to steal income from content creators you have made an active decision to support, redirecting it to one of the largest technology companies in the world.

Avoid Honey. It is ineffective, inconvenient, deceitful, and takes money out of both your own pocket and of any online creators who you are trying to support.
