If you subscribe during the Launch Period you will have a discounted subscription that will not increase for as long as you keep your subscription active. If the subscription price increases at a later date, Apple requires subscribers to agree to any subscription price increases before the renewal date, and you can always opt out. Note: If your subscription lapses for any reason (e.g. cancellation, expired credit card, etc.) you may fall into a higher price tier when you resubscribe.
