Shoot for the moon. Even if you miss, you'll land among the stars, where you will be forced to drift aimlessly farther into the vast, empty abyss of space until a lack of food, water and oxygen causes you to succumb to Death's cold embrace.
Don't forget that this game is really just a parlour game that's been played for decades already. Make your own copy with some blank cards, it's utterly trivial.
We're probably going to stay working with Amazon and Blackbox exclusively—though like I was saying, once we're selling directly off our website next month-ish, rates might be a bit lower (and the expansions will ship intl!)
For what it's worth, when I pre-ordered the McElroy expansion + base game shipping to New Zealand was only $14. (that's about what it cost to ship from the USA to Canada when I lived there so I'm not complaining). I assume that's about what you'd expect when the site goes live for shipping.
