Hopefully, a sponsor might also read this and add his 2 cents. I live in BC, Canada but buy most of my parts in, or from, the US. I pay to have an address at a legit business 3 blocks across the border in Wa. state. When I tried to buy a part from an outfit in Ohio, I received a message from their rep stating that his credit card-approving company would NOT accept the deal because the card-owner's address (mine) was outside the US. His exact words were "we have gys (sic) form up there that try evey way possible to buy stuff that is NOT LEGAL and we do not want our name on anything that is used in the wrong way or gotten through NON-Legal export or channels" I CAN buy the same parts in Canada (at twice the price). He was sort of upset in his response and I got the impression he thought I was trying some skullduggery. BTW, I stop at customs/ immigration on my return and pay the appropriate duties/taxes. I was recommended the business that affords me an American address by a buddy whose son races motocross and he often buys parts for their bikes in this manner. Anyone have factual input about buying cross-border?
