Hiya,
It appears that there is some confusion about what a Domestic Exclusive is. It means that if you live in the U.S. - you can ONLY order this item direct from Sideshow.
If you live outside the U.S. (anywhere outside, including Canada), you can either order it direct OR contact your distributor to see if they will be importing it locally.
Domestic Exclusive also means that in edition defined as "domestic exclusive" there are only 500 pieces. I believe that in this case there is also an International Exclusive planned that is no different other than the words 'International Edition' marked on the base with a separate allocation quantity to draw from so that we can guarantee pieces will be fulfilled for our very loyal International distributors. If there is an item for which an International edition is justified, it will usually be a very small edition.
Think of it as the Domestic Exclusive basically being the Sideshow Exclusive, and the International Edition being like a 'regular edition' which we don't actually sell on our site because it's specifically for our distributors.
(unless there are a few left over after the distributors' sales orders are filled, like with the Patient Zero PF)

Hope that clears some of it up!
