I am flying to Pisa from Australia via Singapore, I need to buy a bottle of perfume along the way as a very special present for a special niece. It is Gabrielle by Chanel.A new product I believe. My question is where along the way would I get the best price for the genuine product? I have never in all my years bothered with perfume or scent as we called it in the olden days! I know one of you would know and be able to steer my in the right direction. Please help
