That's an odd one, glitch on the app perhaps, try a cache refresh and reload.How comes whisky for example labelled with Prime Delivery has fastest delivery Saturday?, isn’t the point of prime that you get it next day.
I sometimes buy a bottle of whisky on Amazon, just find it strange why some stuff is next day and other items with a prime option 3 days from now for delivery. It’s the same for all bottles of whisky.
Just searched whiskey, clicked the prime button on app and got pages showing delivery tomorrow, 12th May.
