A certain number of tickets on each train are sold at a discount (so: 29 euros for a seat, 39 for 6-berth couchette, 69 for a 2-bed sleeper). They are only available at a CD international ticket counter. They can sell out, which puts you back to the fare they quoted you above.
Well, at least the Czechs do the decent thing and publish information about international special offers in English too. The same can't be said about the Hungarians, who only publish this information on their website in Hungarian (their English website is woefully basic).
