The artist provides us with the product they choose to sell. Because we receive product directly from the artists, we sell music that comes in a variety of formats and packaging types. Some discs are shrink wrapped. Some are not. Some discs are gold-pressed CDs. Some are CD-Rs. We display the product type (CD, CD-R, Vinyl, etc.) on the album page, so check there if you need to know ahead of time what kind of item it is.
A Pro CD-R is a professionally duplicated (burned) disc with clean printing and retail-ready packaging. (For CD-RP – the “P” stands for “professionally-manufactured”)
A Homemade CD-R is one that is NOT burned by a professional manufacturer. It is one that you burn at home and package yourself.
A CD refers to professionally replicated discs, made from a glass master.
