It is difficult to be attentive to a discussion that doesn't exist.
Well here, you selectively didn't quote most of the context and didn't address to any of the following:
That's not really a useful discussion though.
That's like asking "have you ever purchased an item at a grocery store where the price was clearly indicated?"
And I don't buy stuff because it's on sale. I research and decide what I want to buy, I look up the lowest historical sale price, I set up an email alert to notify me next time the price reaches close to or below that price. No (paid) advertising involved.
Right, that's all either not relevant to me, or stuff that I just explained I wasn't talking about.
I try to buy everything direct from the manufacturer where non-sale prices are purely to clear out discontinued stock or to discriminate against people who need the product immediately. I also preferentially purchase from manufacturers who never have sales. If you want to pedantically refer to sales as advertising, fine, we should get rid of those too.
Sugar cereal is disgusting and shouldn't be allowed.
Alternatively, I could accept, arguendo, that you are an exceptional person for whom advertising is not relevant.
Bully for you, but that demonstrates that you are, in fact, an exception to the general rule as to the relevance and effectiveness of advertising upon the general public.
I'm obviously exceptional by virtue of my avoidance of media ads and/or recognition of how worthless advertising is.
