lol @ all the misinformation in this thread.
FYI, USPS first class international can go up to 4 pounds. The 13oz rule only applies to domestic mail within the US, but shipping from US to Canada can have a max weight of 4lbs for first class, which is the cheapest shipping option for USPS, which is also much cheaper than international Fedex or UPS. Last time I shipped a full sized Filco last week, the whole package including the keyboard, caps, and thick packaging was a tad under 4 pounds. a TKL version should also be less than 4 pounds, so shipping price will be between $12.55 - $15.95, depending on exact weight of the TKL + packaging. Basically oneproduct was correct.
