No problem. Having my husband in Austin and me here has resulted in some seriously weird customs issues - I try to help wherever I can.
Oh - one thing to remember is that if you're ordering a sewing machine, or sewing machine parts, you are essentially duty free - if it's made in a most favoured nation. So my bernina parts (Switzerland) are essentially duty free, all I have to do is pay GST. And the feet are about half the price they are in Ontario.
