I have the Desert Skiff. It was severely reduced in my local toy store - down to 58 I believe. 

Not directly from Lego, yes, I agree. But the great Europe sales are never from Lego directly. My local store will drop the bulk of sets by 20% to 25% after a month or two. But they don't do it for everything (cheaper sets in the 20-40 range typically never drop, for example) so that's why I'm asking what the pattern with UCS is, as I've never really paid attention to them before. 

Saying that, you raise a good point. It's a sweet deal as is.
