Sorry I have not done anything like this before. Through paypal, I meant that you would charge say $10CAD on your site, when the user logs in to their account, the charge is automatically charged in their currency. But this wont be displayed on your site, only a figure of $10.

It really depends what kind of a service you are giving, in what quantity and how often you need to transfer it back home. For example paypal and many credit card companies take a small percentage of the transaction. Google checkout is another solution to this. If you only transfer the money once per quarter then you may save money when converting currencies
