If you can log into the Kickstarter site yourself, you should be able to fill out the survey anyway. Just look for an orange bar across the top of the screen asking for action to be taken.
Failing that, if we don't get your survey response by the time your package would be ready to ship, it will get bumped back in line. We'll probably check again before we move to the Patience packages and once more after. But keep in mind that it will take at least two weeks (probably three) to reprint the books, so there's plenty of time left to get that survey in.
I already answered your email about this, but for the public (since you mentioned here): The $37 is a typo in that particular survey. I copy-pasted the text from another reward level with higher shipping costs when I was sending out the survey. $10 will cover the international shipping, and no one is asking anyone to send more.
Actually, the error was a result of me picking a color off of a digital chart of the possible twill colors, and that chart being really, REALLY inaccurate. Like, far more inaccurate than when they just say, "Keep in mind that all monitors display colors differently." So for the fix, I gave the stitcher a PMS color to match, and it came out fine.
