Works out to be $488 after $100 cashback.
PLUS if you are an existing Vodafone customer and you purchase another new phone/plan, you get 10% off your access fees - another $34.50 off.

So all up *for existing customers* you get the phone for $453.50!
You can now use the $25 credit code to add a bit more value. You can't use the 10% off code as well though so you need to chose which works best for you
