Things that make me go hmmmmmmm

I saw this commercial today for some tool that will get rid of your pet's hair so your pet won't shed, thereby eliminating the pet hair that gets all over the carpets, couches, etc. All fine and dandy so far. But, then they went on to say that they are including, FREE OF CHARGE, a lint remover that will also remove shedded pet hair. Now, why would you need this if the darned tool that they are sending you will eliminate that shedded hair??? That question has been driving me nuts all day.
