At this moment it's not even posible to purchase train tickets that far ahead.
But for dates as far ahead and cheap as I could imagine (looking in July for this), right now, just for a heads up indication -
Stockholm to Göteborg
Monday evening - 30 euro
Tuesday lunch - 15 euro slow train, 30 euro fast train
Göteborg to Malmö Friday
A bit less than 15 euro
Malmö to Stockholm Saturday
30 euro if lucky, up to 60 if not in luck
It's the accomodation that might set you back though.
Göteborg is free at my place of course, but Malmö and Stockholm might run up a bit.
I can stay free in Stockholm with friends, not sure I'm able to fix you in as well though.
Malmö I'll need to find somewhere fairly cheap to crash as well
OK, train costs are very doable
Maybe I can find youth hostels or B&B in Malmö and Stockholm if I can't crash at your friends' place, no problems there.
Wednesday I have my last exam (for 2 weeks at least), so I'll be able to plan this more specific.
