Is there a tip to get even cheaper prices displayed in the best price finder?

Choose off-peak hours

For travelers who are not bound to specific departure times, it is advisable to select train connections in the early morning or late evening hours. If you are not tied to a specific travel day, you can choose off-peak hours and, for example, avoid traveling directly before the start or end of weekends, holidays, or public holidays. Trains are usually less crowded at those times and generally cheaper.
