It's a scam, it lets storefronts control what discount codes to show you, and only pretends to search the internet for codes.

Installed for a couple weeks, it never worked(never had a working coupon code). I promptly uninstalled

This add-on is a scam. It hijacks content creators' affiliate links and doesn't actually find you the best promo codes available. They also sell your data.

This add-on is a scam. They do not apply the best coupon codes available, they apply whatever code their partner companies pay them to apply. Search for codes yourself and don't allow this scam product to steal from companies, consumers, and their partners.

Horrible, horrible scam, incredibly predatory and harmful business model. Search "Exposing the Honey Influencer Scam" on YouTube. Honey & PayPal should be ashamed of themselves.
