Game Of Thrones: A Guide To Westeros Puzzle

Thinking very hard about buying the Game of Thrones: A Guide to Westeros Puzzle.  Buy myself some thing cool every year for a Christmas gift.  The only trouble is I have only found one listing for Canada and the rest come from the States.  The Canadian listing is on Amazon.ca but not from them but from a user that uses there online storefront.  They are asking (as of November 26, 2013) $74.95.   Over at Amazon.com they are selling it for $59.55 US.  Then he HBO Store wants $59.99 again in US money.  Going to look into the Amazon.com to see how much shipping and the exchange rate/tax will come too.  Just to see if it will be cheaper than the guy on Amazon.ca.  Will be back with an update if I decided to buy one.
