There can be 175+ different territories that you may sell an app in, each with a different local price point. You also can't expect to simply show a converted $US dollar amount either as you may want to do price discrimination (so that the app is cheaper for regions that cannot afford the exact $US equivalent).
Overall options seem to be:
1. Don't show pricing and leave it for the App Store to display - the most common approach
2. Only show $US pricing on the website and let non-US customers manually translate to their local pricing - not a great experience for non-US users
3. Manually or automatically sync pricing on the website display with the actual current App Store pricing. This is quite a labour or integration intensive task and I've only seen this been done by large vendors

It's a worse experience for someone to convert USD to their currency (instant mentally or 2 seconds on Google) compared to launching the app store, installing the app, getting to the purchase menu, and seeing the price?
They don't even list the price along with their other products: https://obdev.at/shop/index.html
