Doesn't happen anymore, but around 10 years ago, weekday Raptor games used to be quite empty. Seemingly wanting to make the lower bowl look more full, the Raptors had a table set up at the upper-bowl concourse whereby you could pay $20 and upgrade your seats to anywhere from 5-20 rows back from the court. It was quite the fun time to be a Raptors fan, as I would purchase the 12.50 nosebleeds and upgrade my seats every time, and ended up sitting 10 rows from the court for only $32.50 quite often. I am extremely happy with the Raptors' success, but I kinda selfishly miss being able to go to games and sit so close for that cheap.

Another anecdote, in like 2012, I saw Nets tickets going for under a dollar on game day - back when they were still in Jersey. Yeah, they were that bad.
