I just wanted to let you guys know that my case of 12 Bust-Ups arrived from AFX today. I have to say, these are very cool.
My ratio was the following:
3 Stormtroopers - each a different pose
3 Darth Mauls - 2 regular, 1 variant
3 Darth Vaders - 2 regular, 1 variant
1 Count Dooku
1 Darth Sidious
1 Royal Guard
I'm pretty sure this is the same breakdown as previously reported by Jay and Jim.
The price was a little ugly living north of the border:
$59.99US + $23.95US shipping + $28.82US customs = $112.75US
$75.71CD + $30.22CD shipping + $36.36CD customs = $142.29CDN
Shipping and customs pretty much doubled the price!

So in the end, it works out to $9.39US each, or $11.86CDN each.
However, if you take into account the free 2-pack of Holo Vader and Maul, it comes to $8.05US or $10.16CDN each.
$10 a piece is a little steep, but at least I can be sure that I get one of each Bust-Up, including the 2 variants and 2 holos.
Plus, I've got an extra regular Darth Vader and Darth Maul to trade for the Series 1 Luke and Yoda that I still need.
