CURRENCY Question

I have searched the documentation and forums but can't get this
straight re: currency.

We have a Canadian store selling in either CDN or, for US customers, US
currency.

I have set my feed options to Canadian currency. I upload my feed with
a currency column specifiying CDN currency. My prices in the feed are
CDN prices.

Is this acceptable/correct? The documentation seems to indicate that,
and there is a Canadian currency option in the feed option preferences.
Does froogle convert and display a US price for US customers on the US
froogle site?

Or do I set everything to USD currency? (it seems that all other
merchant products are US currency).

Thanks, Terry
