I forgot about the cigars, yes these are worth buying duty free, and as the smoke doesn't go into your lungs I'm not as worried about the effect on my remaining lung. I like H. Upmann, a very mild smoke with a subtle flavour. Like you, a box of 25 transferred to the humidor will last me years. I don't like a long smoke, I prefer panatelas, I still have some from my last visit to Sheremetyevo some years ago, when you could fly there direct from LHR rather than having to fly via BEG.
