Don't ask me why - Eurythmics

You could have a worse deal than this one: for the price of a regular CD single you got a 7" square box set including a CD single with exclusive tracks plus a big poster, with pictures on both sides. Well, the poster was folded of course, so perhaps some people may not have enjoyed this a lot, but it's still a great set.

As for 'exclusive': the two exclusive tracks here were only issued on a promotional CD single, so 'normal' people got a good deal on this front too.
