Some time back someone advised buying from Amazon in US$ rather than NZ$, whereby the conversion would be done on the credit card and would be cheaper than having Amazon do the conversion.
I made the mistake when I bought my kindle and bought in NZ$.
But now that I am buying ebooks, I want to change back to buying in US$ but can't find out how to do this. The only available option is to use the 1-click option and there is no opportunity to choose to buy in NZ or US$.
Is this able to be changed
