Thanks for the offer, but it seems like they also have locked down a Canadian service:

For everyone who pre-ordered the book to Canada (or didn't pre-order it because shipping prices were too high), they're going to be able to reduce them to around $18 from whatever ridiculously high level they used to be at. I don't have an exact schedule for when that is going to be updated in their order system—probably tomorrow?—but either way, anyone who ordered at the old price will get the difference refunded.

I'm not going to announce this on Twitter or anything until I'm sure it's in-place on the Ookoodook site, but it's definitely happening.
