What does "tasteful with money" mean in that following sentence?
▪ Show off how tasteful you are with your money by buying it.

You have given us no clue whatever about what "it" is, but it must be something tasteful (probably something unpretentiously artistic).

I think the writer probably means this.

Show off how tasteful you are with your money by buying it.

It was like this: Show off how tasteful you are with your money by buying these comics.

I'd write: Show off how tasteful you are by buying these comics.

Thanks Clive 😌
Hasibrahman by buying these comics.

OK. It's possible that the sentence is tongue-in-cheek (facetious, joking) because 'comics' don't strike me as a particularly tasteful purchase.
