Thinking about doing a couple of CD or CDR runs... and can't think of any reason to pay for a UPC code. I don't plan to have it distributed through Amazon or anywhere like that. Is there any other reason to have a UCP?
Unless you are intending to sell your product through major outlets like Wal-Mart, Amazon, or any other enterprises that use barcodes for stock-keeping, there is no point in wasting money on one.
