I haven't been able to find any comments/posts for the US distributions of Armageddon so I wanted to collect together a couple listings for store-exclusive Armageddon albums available at US distributors with exclusive stuff. Here's what I've found so far:

That's pretty much it, I didn't dig very far into Amazon since there's so many listings from other vendors but if any other exclusives pop up I can add them in here.
