I like to buy things myself, but I generally have a purpose of some sort, or having used similar things, am targeting a very robust thing that I can camp on and use for a decade or two.

A good friend is always buying products, trying them out, gadgets and such. And they spend a lot, but they are always super happy with their new things and frankly, give me a lot of their older things so they can get more new things!

(that's crazy, but they do them, and we are great friends, and I make good use of the stuff falling my way too)

That said, I generally don't gauge off the AD campaigns. Big spends are a rational choice as are modest ones and or guerilla type campaigns, which the latent rebel in me is a sucker for.

What I can say, knowing someone like that, is they are entertained by new things. I'm sometimes that way, but it's rare. Like a great watch might do that, or some cool tech thing I can use with my hobby computing / making. But, my entertainment is more centered on doing stuff, and or hanging with people, maybe doing things with them.

I do hate getting a thing that sucks. Shuts me down for quite a while.

I LOVE a good score, like a thing that is just awesome and I know it will perform for ages.

Basically I can use targeted ads as a free product discovery engine. Seeing an ad doesn't mean I'm going to mindlessly buy it. I know some people do that, but there's a way to make use of the situation.

[1] there might be an evil conspiracy among kitchen table manufacturing companies who teamed up with Hollywood producers to sell me the idea that I want a loft style new kitchen table :)
