The season is now ended, but it lasted for months. Because of Covid, many U of I students abandoned their apartments months ago. But some stayed.
So the exodus didn't happen over one week in May + the late July-through-mid August lease expiry period.
In all, I collected about 5 years worth of laundry detergent. Six computers. About a three year supply of black & green teas. Quantifying the food haul is tough, but I think two of us could eat for a month on what I brought home.
But if it's specifically TODAY, the answer is nothing. Yesterday it was four yellow onions and a Totes umbrella.
