I was wondering if anyone has had any experience in crossing into the USA to ship packages? I live 2 minutes away and I have a HUGE package of motorcycle parts (panniers and rack) to ship. I am not selling them in the USA as the transaction happened over the net but, just crossing into the good'ol US of A to take advantage of extremely low shipping rates. When I cross the border, they alway ask me, "are you leaving anything behind, are you shipping anything?" and I never am but I wonder if I have to pay some sort of shipping tax if I actually AM shipping something within their country, haha. Any wisdom would be great! Thanks.
