Hello @JPiecyk,
SuperSaver Tickets are cheaper tickets that are not refundable and not exchangable. They are also only valid on the selected train (normal fare tickets are valid on any train for the selected traject)
These tickets are available from 60 days before the validity.
I hope I could help you understand this offer. We are also available 24/7 via phone if you still have any doubt 0848 44 66 88.
Greetings,
BrendaD
