When they say they will find the best coupon, they are lying. They will present the coupon their customer want you to see.
When they ask you if you want to check for coupons when you used an affiliate link, they will also simulate a click from you on their own affiliate link to steal the commission.
No wonder Paypal bought them 4 billions. It's a scam, it's a theft, it's disgusting. Run away from them, search for better coupon though any search engine and give money to the right person when you click on an affiliate link.

Think its found maybe 2 coupons in the 4 years ive had an account.

It's a scam project.

Scam. Steals affiliate links, gives you worse or no coupon codes instead of applying the best ones available. Report this extension as fraud.

scams run by garbage human beings

After finding out this extension openly steals the commission creators are meant to gain through their affiliate link, and also that their cash back is measly in comparison to the commission they gain, I see no other choice but to uninstall. I guess it really was too good to be true.

Changing my cookies in the background with purposefully deceptive tactics. Sketchy ever since Paypal took over, not worth it anymore. I ALWAYS easily find better coupon codes with a simple google

Holy sh1t! Don't download this f*#king crap! They steals money from creators with sponsor links by secretly changing it to their own cookie. Uninstall this ASAP and never look back. This should be the end of Honey and PayPal for their deceptive practices. F*#king no shame in the shit they are doing. F*#k You PayPal!
