Borderlands 3 (Steam/Epic) is on sale for 56% off at IndieGala for $26.37 (Base game).
Deluxe Edition is $35.19 and Super Deluxe is $43.97
It's the lowest I've seen it go yet.
Please be gentle; I don't post deals often. Link below.
EDIT: You also get Men of War: Assault Squad as a free bonus game, and IndieGala has tons of other free dev games as well
