For sure. An implied sense of false urgency is the point of sales in general. There’s all sorts of psychology around manipulating people into buying things.
I just think that acting as if there is some sort of grammatical error or gap in logic is missing the fact that in language, people imply things. And an ad implying “you’re going to buy this, so you better do it while costs less” isn’t too hard to follow.
Yes. And that is the point of ads. And we can agree that it’s not great to manipulate consumers.
but “you can never save by buying something. I save if I don’t buy” is NOT identifying the presupposition, and therefore not rejecting the presupposition. It’s just stating that the original statement has a logical flaw. Which it doesn’t have any logical flaws if you accept that language has subtext.
“I dislike that the implication is that you can only compare to buying at full price, when there are other options like not buying (which saves 100% vs full price)” identifies the presupposition and rejects it.
