I have the opposite problem at ZRH. It grates on me that at ZRH if I am connecting non-Schengen to non-Schengen (I think that's the it? it might have been something else, I'm not sure, but some ways of connecting will make you miss out on duty free shopping unless you go through immigration) I have to go through the Schengen immigration to get to the duty free shops.

Immigration guys find it amusing when I jokingly grizzle and tell them that all I want to do is to go to a duty free shop and I have to go through immigration just for that. Exiting is even funnier. They sometime say "You're leaving already? You've only just arrived!" "Well I only went through to do some shopping in your duty free shop... because there's no Bulgari skincare on this side" and they laugh.

That's the only very easily accessible place I have found other than IST that stocks the Bulgari pink skincare range.

Before anyone says I must be an infrequent leisure traveller to enjoy the shopping aspects, well... perhaps think again. For the time-poor, airport shopping can be extremely useful because there is usually a bit of 'dead time' during connections, after check-in or if there is a delay.
