Apple Arcade and Apple TV+ are $49.99 each per year
Not 100% sure this is a deal or if this is the regular yearly rate compared to to paying $4.99/month. But for 12 months I am seeing $49.99 for each.
You won't see this option unless you're already a subscriber, but you can do it even if you're on the free trial - so sign up for a free trial and then switch to the yearly plan, which should be $49.99 (you are getting 2 months free). Navigate to your active Subscriptions on your iOS device or Mac and select the yearly option.
