A pre-ordered title will typically download before its release date. It is stored invisibly on your system until the release date, after which it will appear automatically. Some titles will be made available for pre-order before an official release date has been announced. Once announced, this information will be reflected throughout the movie store.
Your credit card will not be charged until the pre-ordered title is released. If your credit card is declined, the downloaded title will not be playable. You may update your credit card information and repurchase the title to make the already downloaded title playable.
Prior to being available for download, pre-ordered titles appear in a separate section on the Downloads page. You will receive an email when a pre-ordered title is moved to the end of your download queue. If you already have many titles scheduled for download, you may choose to change the download order to make the pre-ordered title finish sooner.
