That's a great idea, I get this gut feeling/fear though that it might introduce some extra complexity. I might be able to do that at least for EUR/USD/GBP but I suppose have avoided it until now to keep things simple. Will have to think that through more.

Sure. I see your PayPal subscription is $23.95 per month - which is fine, there's no need to change that. I'm just thinking from a UI perspective you could try using money.js (1) to show to the user the current price in their local currency:

Mystery sweets from Japan for £15.10 ($23.95 USD) / month
