While I'm not a fan of "Up To" sales here we go anyway. I'm not sure if the results will be the same for everyone as you must be logged in to view or you'll just get an empty page.
For me, titles listed have discounts varying from 9% to 61% (despite the claim up to 75%)
Not sure if anything will overlap with the other deals listed with codes so be sure to check them out first.
If you are looking for something chill and on the cheaper side, I can recommend Puzzling Places currently $13.99.
For some reason you have to be logged into an account to see any deals.
