I noticed the prices for the bus from Prague to Munich are two fares: the savings and the standard. I'm assuming the savings is the non-refundable ticket?
That would come out to 29 Euros per person, am I correct?
Yes, you are correct. The non-refundable, Savings Fare tickets go on sale 92 days in advance at 29€ for the first person. As the date approaches, and lower priced tickets sell out, the price is higher. Standard Fare tickets are always available at that price and are fully refundable, exchangeable.
