It seems the voucher codes they 'find' are not the result of them searching the Web.

They are simply codes provided by partnered businesses and may be beaten by codes you can get by searching yourself.

If true, then this is them outright lying to the user.

And you know, if they don't find a coupon code for you, one might still be at least a little annoyed that the original 'salesman' didn't get their affiliate commission; it instead being pinched by another.

I think in addition to the coupon thing, they had/have some cash back points? In any case, as someone who filters affiliate links, I can't understand why anyone would want to preserve them. Making them useless by having the user's browser automatically inject one seems like an awesome feature and a great social good, even without the user getting part of it. Affiliate programs are a direct cause of a lot of the spam on the web.

It should bother you if 10-30% of your price went to whoever last got you to click on a link.

Yeah, they pass on 80 cents of the $35 commission they get from Nord VPN when they hijack someone else's affiliate link. And it's 80 cents in "points." So you have to spend more to even use those.

It's a scam in partnership with the on-line shops. The consumer loses, the reviewer using affiliate links loses, and it turns out the extension goes further by occasionally making up discounts that don't exist (this will be in the next video it seems), so the seller gets screwed, too!

Well some people actually do believe in giving credit to the person who helped them make an informed purchase. I have gone into a store and had a worker spend like 20 minutes showing me things. I wasn't ready to buy but when I was and came back I had another worker try and help me but said to them the other worker spend a lot of time helping the other day I would like to buy it through them and was sorry.
