im from Canada and I've paid roughly at least 3k in the past year in duties alone. Then again, canadian duties r quite crazy.. Up to 33% in some instances. They also charge 20 bucks for customs handling on anything over 60 bucks. So basically I got a dumb watch strap for 65 bucks. The shipping was 10, and the customs handling was 20 bucks and they also taxed me 20 bucks for custom fees. So total i ended up spending 115 on a watch strap which was listed on Raku for 65.
On the other end, I get lucky sometimes and my leather jackets 2k+ value just slips right through customs.
