Maybe, it depends on the web store, and which currency they use for international orders. Some are smart and keep prices listed in US dollars. That way if their home country currency goes down, they don`t lose out on sales.
A few weeks ago was looking at web store in Poland, and using their currency pull down menu choices, I could save as much $5.20 CAN on a kit in the thirty dollar range if opting with the Polish Zloty, as opposed to going with the Euro, or most expensive US.
