Amazon has ESPN's 30 for 30 Collector's Set on Blu down to just $49.99 for their Deal of the Day. That's the lowest it's been I believe. It's a great set, and definitely worth watching for any sports fans out there.
This set which includes "Catching Hell", "The Fab Five", and a bunch of other movies. From what I gather it is the second set of these movies, but I might be wrong.
