By that measure pretty much every product except the most generic crap is unique, but that word means more than just "slightly different".
Just because you'd prefer others be more stringent with it doesn't mean that everyone else is lying.
A cable package or car loan does not magically become a GREAT DEAL just because a billboard said so. We're just used to constant lies and aggrandizement in advertising, so all that bullshit looks normal, entirely expected now. It's still bullshit though.
