Actually we only can set domains price with default currency as the base currency (which is USD in our case). It is not possible to configure them to use any other currency as the base currency.
We have a big issue because all the registry that charge us in € due the constant currency fluctuation. Is a headache stay every day changing that.
we suggest to be able to set domains price based in Europe or charged in €, in euro de default currency and domain based in USD, with USD like default.
