We were able to add Prague to the front of a long trip through Europe. Most of the train tickets that I have booked have been through the DB site.

Logged in to my DB account this morning to buy Prague -> Munich for Tuesday 20 July and it priced at 96.30 Eur. (9:04 am -> 15:02) 2 travellers (age: 49, 13 years), 1st class, Praha - München

But...received:
Unfortunately there is no online booking possible for the requested connection. This is due to one of the following reasons. Neither an Online-Ticket (for self printing) nor a seat reservation can be offered. The deadline for booking the requested journey has passed. For deliveries inside Germany the deadline is 2 working days. For deliveries into foreign countries the deadline will be up to 8 working days (Mo.-Fr. until 16:00 o'clock).
For alternative connections, please start a new request.

So, logged on to Raileurope where the same train prices out at $303 USD!

I've tried the www.cd.cz site but am having trouble navigating. Is there an English language version I'm missing?

Is there another site that I should look at for better pricing rather than Rail Europe?

Many thanks!
