Products are shown on Product Pages. These are made up of Product Formats and in the case of music products, Tracks.
Product Pages will hold all the relevant information of the release together in one place on your store. This includes release-level information such as Artist Name, Release Title, Label Name, Release Date and Artwork.
Within the Product Page you will find Product Formats, they represent the various iterations of the product available for sale.
For example, for a clothing product each different size will represent an individual Product Format. For a music product each digital format (MP3 / WAV / FLAC) will be an individual Product Format, as will each physical format.
