From personal experience, in Iran, a case of beer, 24 x 33 cl cans cost exactly the same as 4 bottles of whiskey (of the Jonni Pedestrian shape)..... summat to do with the volume of 4 whisky bottles vs the volume of above mentioned case or slab of beer.........when moved in a Turkish truck!
Needless to say, my beer drinking suffered a bit of a drought in those days....
