The reason im asking this question is, I am launching an app and it has different pricing based on different countries. So, the transaction doesn't happen on the client-side, its simply displaying the price of the app. The actual charge happens via Apple.

Big companies usually have different websites for different countries. But for smaller countries do they simple just display the price for the main country they sell in and if a user is buying from another country they rely on their payment gateway to display the local currency?

Dont hate aussies , Im an aussie :)
