Swedish rail offers a program called Just nu for reduced price tickets. Just nu translates as "just (for) you" I find no link on the Swedish web site. Had I not seen this in a Steves travel book I would question that Just nu exists, but I am sure that it does. Please reply if you know how to raise Just nu.
Actually, "just nu" translates to "right now". Here is the link on SJ about it:
