Does anyone know the price of a bottle of Grey Goose (1ltr & 70cl) at Dubai Airport DXB?

I know someone who's returning from Australia soon & wanted to ask her to get me a couple of bottles of Grey Goose vodka on her stopover. However, I'd like to transfer the money into her account first so does anyone happen to have any idea how much it'd be in Dubai for 1x1litre plus 1x70cl bottle? Thanks
