Short version: Can I buy tickets for Hungarian trains online somewhere?
Long version: In two months, I travel from Czechia to Hungary, namely Jindřichův Hradec - Debrecen and back. Czech Railways offer me the following tickets:
Jindřichův Hradec - Debrecen and back for
~ EUR 120
Jindřichův Hradec - Budapest and back for
~ EUR 50
This means that if I got the ticket for Budapest - Debrecen and back online for
< EUR 50, I could save a reasonable amount of money. However, I found no e-shop on http://mav.hu/english/index.php
