Honey is a scam that poaches affiliate and referral links (or turns your purchase into a "referral"), even when not finding any coupons or "deals", in addition to flat out lying about the existence of working coupon codes. I used Honey long before PayPal bought it and I don't know if it operated on the same mechanics then, but now it is absolutely just a way to funnel money to PayPal via affiliate link poaching.
