But surely if you just bought a <Roomba> and like it and intend to buy it again as a gift then you don’t need an advert for Roombas - (and showing you such an advert followed by you buying another Roomba is making the advert look more effective than it was) - and you definitely don’t need an advert for Bissel or Dyson, and you definitely don’t need a dozen adverts for Amazon PLINGBA BEST VACUUM, TYBCHO VACUUM EXPERT, DAOLPTRY VACUUM CLANER etc etc?
