I know that I probably fail at this, but I try to actively not buy brands I notice ads for and instead always go for the brands that are unknown (or less known) to me. The advertisers probably still trick me, but I try. I don't care one iota about what my choice of brand/product signals to other people (why would I? I don't care about anyone elses opinion about me in the first place).
