This almost deserves its own thread...
Best Buy has a pretty awesome Batman sale going on right now.
I picked up all five seasons of The Batman for $5 each.
Also picked up Year One and Superman/Batman Apocalypse for $5 each.
If I didn't already have them, they also had the first three sets of Batman: The Brave and the Bold for $5 each - and the 5th (last) set on sale for $15. They didn't have the fourth set, so I dunno how much that was supposed to be.
Additionally, they had one random set (volume 3) of TAS for $15 and volume 1 and 3 of Batman Beyond for $10 each.
Long story short, I bought $123 worth of Batman for $35.
