TLDR; This add-on not only rips you off but your favorite creators as well.

This add-on steals money from creators with sponsor links by secretly changing it to theirs. It also does not do the thing it's being advertised to do -aka 'saving you money by looking for coupons'. They do not have many of the working coupons, and they do not add them to their database even if a user submits said coupon to them.

You're better off not using this add-on, even if you can't be bothered to find coupons yourself. Best case scenario, you are not losing anything by not having it. Worst case scenario, you and the creators you enjoy get ripped off by the shady developers of Honey.
