Ah. I didn't see the $699 and I guess $999 give you one of each stretch goal unlocked as well.
I guess that brings the $699 down to something like $14+ per 'item' though you're stuck with one of everything and no multiples (but sure, why not trade around).
And yeah, the Mayhem is about $10.50 per item, though you can 'army build' your stuff better with a selection.. but $1K.. yeesh. But it's the only one that makes sense for a group buy.
I can probably toss in $100 or something if we want to try and get a pot together for that. I fucking don't need any WWII figures, but some of them seem cool.
