Clothing wise, I only replace my pants when they threadbare at the knees, end up with a plethora of free t shirts, and get the odd sweatshirt at uniqlo every couple of years because it's cheap and decently durable. I bought my formal wear a decade ago and I haven't gotten any fatter, so I'm not hurting for a new suit every couple of years.
Foodwise, I only buy store brand because it's the same stuff but cheaper due to a lack of a marketing budget, and although I do order takeout it's not like I was wooed by the targeted advert for the local indian place—I was wooed by seeing them throwing the naan at the back of the tandoori right in the restaurant. I always opt for pickup instead of app based delivery which can cost more than the entree.
In college, I used my highschool beater to get groceries, these days I use public transport and don't own a car. But if I did have a use for a car, I'd go with another beater over spending multiples more to go between the exact same points A and B in the exact same time using about the same amount of gas. Never wrapped my head around why people even buy new cars, unless handsfree bluetooth audio really is worth dropping another 10 grand or more.
Other than that, I only really spend money on experiences, not material goods. I guess you could say then that I'm not immune to an event ad, like if my favorite musician comes to town, but that's really a notice rather than the modern interpretation of advertisement. I see an ad for some blue tint glasses or a subscription box for hatchets and leather products, I think, 'what the hell is the point?' Based on other comments in this thread, I get the sense that I'm not alone with this mentality.
