Maybe I was lucky. I don't know since it was the 1st time I ordered gear from Europe. I was counting on the possibility of having to pay taxes but even considering that, it was not a bad deal (I paid $1720 CAD with the currency exchange in December, now it is better $1632 CAD) and I got my KPA as soon as it was released in Europe. My experience when ordering from US so far is that I never had to pay taxes/duties when shipped by USPS (Post Canada) but I paid taxes+brokerage fee always when using UPS, Fedex, ...
You are very lucky my man! I used to get that at the border, everything passed through no problem with USPS until they caught it once, now everything gets scrutinized!
