My preferences are based on my understanding of myself.
I do not have those problem addictions. Of course I am going to comparison shop for any large purchases. I am good enough about controlling spending that excess junk isn't one of my problems.
But what I do have a problem with is coming up with creative ideas for people in my life. So, for example, I would have never thought to look for https://www.zazzle.com/cup_equation_love-168099175298227864. But I'm very glad that someone out there knew enough about me to guess that this might be an item that I'd like. And my wife liked the cup a whole lot.
Does this happen often? No. But I'm perfectly happy to pay a premium for a product when an advertiser gets it right.
There are always situations where an advert is useful and we remember those. However, when an advert causes you to spend more than you would, you have no idea it has happened.
Maybe you truly are above the influence of advertising. However, almost no one believes that they are affected by advertising yet clearly almost all of those people are wrong.
I find it safer to assume I am part of the vast majority of people who would be influenced by personalised advertising. Given that online advertising is basically the biggest business in the world, I assume that it would find a way to get money from me.
