Checkout: Digital Files
The WordPress Shopping Cart plugin gives you the option of defining a product as Tangible or Digital, i.e., a physical product or a song, picture, video, WordPress theme, PDF, etc., that a shopper can download after they have paid for it.
This section allows you to specifically define and upload digital files to a secure environment which the shopper can then download once they have paid for it or you can point then to a specific link (URL).
Digital files can be almost anything that you can upload to your server and may be a Microsoft Word document, PDF file, MP3, wave file, spreadsheet, zip or rar file, a theme or plugin/module for WordPress, Drupal, Joomla, OpenCart, or other systems, or even just a link.
