Thanks for getting the coupon code at least.  That brings a single box price down to about what 2 boxes would cost (each) with shipping. 

I'm thinking about ordering 2 boxes - anyone want to lock up my extra basic set of 6 + Jabba for $100 shipped? ($90 for locals)

I think it's pretty clear from the info Medicom has released that we're getting 1x figure and 1x Jabba piece in each box.  The Medicom website clearly (well, as clear as broken English-Japanese translations can be) says:

"When the bonus part which belongs to each box is combined 'JABBA THE HUTT (TM)' you complete!"

I can't believe they would include a unique Jabba piece with the case chase kubrick figure.  That would mean only 1 complete Jabba could be built per case.  Then Jabba himself, the complete verison of him anyway, would also be one per case.  And that doesn't make any sense, since the whole idea of this new Deluxe series is the ability to build the Jabba, which couldn't happen if there were chase build parts. 

I think if there are any chase kubrick figurs in this series, they must come with the same build-a-part that comes with the regular kubrick figure in the case that they replace.  E.g: Let's say Jedi Luke comes with Jabba's head.  and Nikto is a chase figure you find randomly in the Jedi Luke box.  Nikto would then also come with a Jabba's head build-piece.

Logically, this makes the most sense to me.  And also, it's what I'm hoping for.  Since, if the chase figure also comes with a chase build-a-part, that will make the chase figures even MORE expensive then they would be already.
