There're two Chinese online shops doing quite sophisticated shipping to EU countries via UK. This seems to be legal and you get it for the Chinese price.
They are pretty reliable. But in my honest opinion, That kind of money should just be spent in the Dell Outlet. Get something like the Latitude 7270 / 7470 or the Latitude 7275 (Sort of a surface clone). At least warranties would be easier and you have Dell's support.
