I've updated the OP, but a couple updates for everyone:
First: I was incorrect on the poster sizes in the Collectors' Edition. They are actually 18"x26" (46cm x 66cm), not 16"x26" as I'd originally indicated.
Second: We've been able to get a better shipping rate for Canadian customers. If you've already pre-ordered, we've automatically updated you to the lower charge. This should save our neighbors to the north about $13 USD. We will continue to work on getting better shipping rates for everyone if we're able to.
