Has anyone picked up the 3D combo yet, who is an area of the country where bb is allready opened? just curious as to how the exclusive bd disc is pacakaged.

They used a 6-disc case for the bonus disc version. It's the first disc in the set. There's a few featurettes on the disc and they add up to about 20 minutes.

According to the face of the disc, about 20 minutes worth of featurettes:

Organizing A Mutiny (5:13)
Two Jacks (3:52)
Sculpting Mermaids (5:09)
Johnny and Judi (2:59)
The Wild Boar (3:01)

The 3D combo pack also includes a $5 off coupon towards the combo packs for parts 1-3. Those are selling for $14.99 each at Best Buy and Target.

That's in addition to Best Buy already offering a $5 savings if you buy part 4 with any of the others in the series.

probaly cheaper to just buy the box set in that instance though.
either the trilogy set and buy part 4 seperately or the the treasure chest 4 movie set.

Thanks for the heads up on that, I was planning on simply getting a refund on my metalpack case, but a friend decided they wanted the movie as well, she said she didnt care about the bonus disc so i got to keep it for picking up the combo pack for her.

I fit all six discs from the Best Buy Exclusive into my metal box case (double-stacked the DVD and the 3D BD discs on the left, and the Digital Copy and the Best Buy Bonus Disc on the right) and they all fit great. I might look into putting them in paper envelopes, but they hold in place fine right now, you just have to be careful opening it. I then took the 3D edition slipcover and put it over the top of the Metal Box. Very pleased with myself and with this release.
