Correct.
PBK's "free shipping" option (I don't think they offer tracking anymore? Could be wrong) is shipped using Royal Post/Canada Post. So I got dinged taxes and a small fee, not an outrageous $57 UPS rape your ass fee. I ordered last week and it already showed up, so I am happy. I had feared the potential strike.
I guess I can't really complain, because if I bought the tires and tubes locally, I would have had to pay an extra $50 or so.
