When you purchase a digital album, you will find a blue, "Download" button on the receipt emailed once your transaction is successfully processed.
If you have purchased a pre-order, your download button will be "grayed out" and unavailable until the official release of the album. Your live receipt will denote the official release date and time, at which point your download button will become active, as a blue download button.
When you purchase a standard CD, you will receive a physical copy of the album when your order is shipped. Shipping information for your purchase can be found at the bottom of your live receipt, which will provide the most current status of your package, including tracking information, if available.
