You can currently sign up for Apple TV+ for 50% off its usual price. But because it's part of a Prime Day promotion, there's only one, very specific way to do it.

Prime members can access major streaming discounts through Prime Video Channels, including a limited-time 50% discount on Apple TV+.

Right now, Apple TV Plus is just $4/month for two months (normally $9), Paramount Plus is only $0.99/month, and MGM Plus (home to some seriously underrated originals) is also under $1/month for your first two months.
