Even if it didn't have the coupon agreements and lowball coupon offers, shenanigans with merchants, it should have been obvious that they had to be generating income one of, if not both of two ways, shifting themselves to the affiliate for the purchase commission payout, and/or selling your browsing and possibly also purchase data.
In the early days it might have still been a good option for those not initiated into deal finding, too lazy to look and always having their time wasted on sites that pretend to offer coupons too and just want you to click through to make them the last click-thru affiliate. Those days are over.
It doesn't even make sense. Somebody's losing in the scheme. That's the only way it can work. Why would anyone offer you a coupon when you're at the 'buy this shit now' page? The seller isn't interested in losing money.
Depends on the situation. I can usually navigate and compare prices on multiple merchant sites for same or similar items pretty quickly, so it isn't uncommon for me to visit, for example, Lowes, Home Depot, Ace Hardware, Amazon, and possibly others for a widget that costs more than a trivial amount. I'll put item in cart, see shipping charges if any, and if there is a coupon, apply it to see the bottom line price before deciding who has the best deal. Having a coupon to lower the price, can make me choose one trusted merchant over another. If that merchant then makes any profit at all, it was more profit than if the widget was bought elsewhere.
Playing devil's advocate, part of the problem is how many merchants have their affiliate program, website tracking set up. It shouldn't be last click-through gets the commission for the whole cart, but rather, the click-thru right before landing on the site, going to a product page or putting item in cart, then if you're the type of shopper to leave things in cart for a while, each product in cart can retain it's own, original/unchangeable, different affiliate association than other products in the cart.
One thing interesting to me is that the youtube channels spreading this revelation about Honey, aren't mentioning that they are sometimes doing the SAME THING! If you have items in cart from a merchant using the one affiliate per cart checkout, setup, and then click one of their (youtuber et al) affiliate links as the last affiliate link before the purchases are made, they can also take affiliate income away from someone else who was the original affiliate referrer for the rest, if not all the cart.
I am not defending Honey, OR these youtubers. Part of my income also comes from non-youtube affiliate referrals so both of these groups, AND myself, are all taking some referrals away from others that deserved them. Honey is simply doing it on a larger scale and not earning it. Well I suppose it may not be
that simple since the rest of what they're accused of doing, seems even more shady and borderline illegal to me.
