I can't stand the new Zoopla adverts, they really make me cringe. That said, I won't actually stop looking at it (surely everyone already knows that that's how you can be nosey about what your neighbours are selling their houses for).
However ... I will never consider buying Daisy by Marc Jacobs, because the advert makes me want to scream. Also, my mum won't ever by Muller products because she hated one of their ads so much.
