How to get a perfume for free(limited time offer)

So as I was going through my mail today, I found that one website called smartprix giving away one bottle of free perfume as a promotional cause and that also without any shipping fee

So let's see how can we get a free perfume:-

1.Go to the given link below
2.At the bottom of the page there would be an option to get the perfume for free.Click on it
3.Fill out your details

I am not sure by the authenticity of this. But if it comes its not bad I suppose ;)
