> if you're moving house you can just throw out the old stuff.
At my college (UT Dallas), we had on-campus apartments. Not dorms, but an actual apartment complex on campus.
The best place for new residents to acquire furniture was by the dumpsters. It turns out that most people moving out would just chuck half their furniture and leave it by the dumpster. Every year from May to August, there would be copious amounts of furniture at the dumpsters. If you were a new resident, you were quickly told that the best way to acquire a couch was to head over to the nearest dumpster and take what you see.
I attended UTD from 2003 to 2007; I don't know if things have changed since.
