So, it's surprising at first, but as others mention, it seems like a roughly functioning system: The students are rushed by the university to move, move, move. They do what they can which is not much for many, who don't yet have their life in order. Buying too much, too expensive, not downscaling in time, etc, why so surprising? Some universities have a decent system in place for temporarily holding that stuff for other students. For the rest, the locals - individuals and business can come and do the sorting.

Same thing happens on Craigslist: You can post an item for sale for a fair price - and it may take days or weeks - or you can post it free and it will gone in hours (to someone who will resell it perhaps but whatever.)
