Peter, the key terms are "quality," "should" and "years." No one knows what quality the original medium was when they buy a CDR by mail, so the product may not be a quality CDR. Also, no one knows how long CDRs will last on average because they haven't existed long enough. They "should" last forever, but they won't. So they will last years, but how many? As I have stated, I have had CDRs become unreadable by CD players within three years. So is average shelf-life going to be ten? If so, people should know this before they buy.
