Ubisoft has put up a blog post about their Black Friday deals on Uplay and the store, including some Switch, XB1 and PS4 games sold through the Ubisoft Store.
17% off AC: Origins
60% off For Honor
25% off South Park Fractured But Whole
50% off Ghost Recon Wildlands
50% off Rainbow Six Siege
66% off Watch Dogs 2
and a whole bunch more
I'd copy them all over here, but since they have no easy way to find them, you're probably best off just looking for the game you're interested in.
And don't forget you can get an extra 20% off
coupon in the Uplay store using some of those goofy U-points or whatever they are.
