Why oh why oh why would anyone buy 750ml of grape juice when you could buy 1 litre for exactly the same price? Any sane person wouldn't do that. Plus the larger package comes in a lighter tetrapak carton rather than a heavy glass bottle. However when that grape juice has fermented and become white wine people suddenly change their tune. It's the same wine, from the same vineyard packed in arguably better packaging. Let's see just how quickly (or slowly) it catches on.
BTW I wouldn't advise trying to steal this supermarket trolley. My superior observational skills tell me that it has some for of security alarm installed.
