Pre-order items from the iTunes Store on PC
If an item isn’t yet available, you may be able to pre-order and then download it when it’s released. You’ll receive an email the same day it becomes available to let you know when you can download the item.
In the iTunes app on your PC, search for a specific song or other item, then select it.
Click the Pre-order button next to the item.
When an item is available for download, the payment method that you have on file is billed and you receive an email notice that says your item is ready to download.
To download the item, choose Account > Check for Available Downloads or click the link in the email.
To view, cancel or see the expected release dates for pending pre-orders, choose Account > View My Account, then click Manage Pre-orders.
Some albums or collections you can pre-order include a song that’s available to download immediately. When you pre-order these items, the available song is downloaded and you’re charged only for that song. When you download the rest of the album (after you’re notified it’s available), you’re charged for the rest.
