If they have taken your details and entered it into the system that would make you that. It doesn't mean anything in my opinion. I'm in the system but cos I don't buy much I am not really considered VIP. I can see you're in Australia so things should be the same in NSW and VIC.
For example, I'm in the system so I am considered a so-called 'VIP'. However when it comes to the pre-sale. I do not get a call to come in early to choose out what I want. I think that VIP system is based on how much you buy. I don't buy much from the boutique (just a few times a year) cos I buy from a boutique right next to
Gucci that stocks Gucci and offers much better service and gives me a discount everytime I shop there.
So basically it just means you're in the system. Hope that helps!
