… at least not for France and Germany (or unless you are booking at the last minute or don’t care about the price).

That’s my advice after booking a rather complicated itinerary for the end of next week that runs Paris-Nuremburg-Hamburg-Paris. Using the German site saved me at least 50%; you could print out most of the tickets yourself; and they’ve got a very good hotel booking section – definitely recommended!
