Several reasons: these are CD-Rs and, as I said in my first post, I don't want a CD-R, and I'm not going to support activities such as selling unauthorized CD-Rs of copyrighted material.
Do they at least clearly advertise these discs as CD-Rs? When I last ordered from them through their own website (not eBay) some years back they only made a distinction between new and used discs without going into specifics about the condition used discs were in. I only ordered new DIW discs from them (with complete satisfaction).
