Blizzard's Black Friday sale on Battle.net is a lot like Blizzard itself: There's not a whole lot in the way of variety, but what they've got is really good. 

Destiny 2 is probably the biggest deal on tap. The standard edition is on for $40, while the version with the expansion pass bundled in is $68, and the digital deluxe is $75. But you can actually do a little better on the standard release at Green Man Gaming, which has it on for $36. (GMG's Digital Deluxe pricing comes in higher, though, so you'll want to stick with Battle.net if you're after the big package.)
