Read the fine print carefully on the conversion. Don't know that you'll have a choice. They should charge you US currency, and then your bank will convert it. There's a bank charge, and then there's an additional Visa/Master Card charge. I used a Visa in Stockholm to buy and ship crystal. I was floored when I got the bill. The very fine print in the agreement and on the back of the bill does state this. My discount of 5% was offset by the exchange charges. Maybe some of our Canadian friends can give you a better line on this. Have a great time, dispite the conversion.
