This is really a best buy item is 750mL not 700mL.
Grey Goose is crafted in the legendary tradition of the Cognac region, under the watchful eye of the Maitre de Chai (or Master of the Cellar), who uses a proprietary five step distillation process to transform fine French wheat and pure artesian spring water into the World’s Best Tasting Vodka. Grey Goose claim to make the “World’s best tasting vodka”.
What is the price?
Edit: Found it. It's cheaper per litre at Uncle Dan https://www.danmurphys.com.au/product/DM_724017/grey-goose-v… which is a fair comparison if your argument is buy my 50mL larger bottle as it's cheaper to buy more.
