There's a hidden shortcut to save money on an Apple Music subscription

APRapper Drake an an Apple Music event.Apple is quietly offering a deep discount on its Apple Music subscription service, but you have to know how to find it to get it.

We can show you how.

There's a menu hidden in the App Store app that offers an individual annual subscription to Apple Music for $99, TechCrunch reported on Monday. That's nearly $21 less than what you'd pay over the course of a year with a typical $9.99 monthly subscription to the service.

There's one catch - you need to be an existing Apple Music subscriber. If you're not a subscriber, you won't see the $99 subscription option. So you'll need to sign up for a single month of Apple Music before you sign up for the whole year.
