So Ori only ended up being discounted to $15. Hm, I may still pick it up, I don't know. I was hoping for $10 (I thought the whole sale was 40-50% off, guess it was only up to or some bull). Unless you're digital-only, I would not recommend the Wolfenstein bundle. You can get TNO for $15 brand new on the Microsoft Store, and TOD pre-ordered there will net you $10 Xbox credit, both with free shipping, too. I may get Sleeping Dogs at $15. Toyed with getting that for awhile, not a big open world fan, but the combat seems pretty cool.
