I could be wrong, but I think the prices will reset automatically to wherever you ship to. For example, I've noticed all items that come up in US $ in the "large search frame" (multiple listings). When I click on an individual listing, it will tell me what the price is in the country of origin, and then in smaller font it tells me what it is in US $. So I think Etsy will translate everything based on where you ship. Maybe someone knows better than I do, but I think it's in Etsy's best interest to help you get as many sales as possible.
