Dark Greek (Turkish) Coffee Loumidis Papagalos

I have just bought my second order of the Turkish coffee for an Albanian friend who lives in London. This friend is so pleased with the coffee that I have been ordered to get some more. I would like to ask what quantity I would have to purchase to cut the postal costs to the United Kingdom.
My friend really likes the coffee so much . It is the same coffee that I drunk in Albania very strong and in small cups.
