Marlin1975, I don't know if this is nationwide (and it's not on their website), but my local b&m Office Max has 10-packs of Kingston 10X CDRW's for $9.99.
On the utitility of CDRW's, I enjoy burning off 10 hours of MP3's for my portable CD/MP3 player in about 8 minutes. My MP3 player before that was a tiny one that used a parallel connection and took 6 minutes to fill 30 minutes of 128 kbps. Ugh. I also enjoy taping talk radio--Car Talk, Fresh Air, etc.--and burning it to CDRW (full 16-bit/44.1kHz) so that I can play it in my car stereo. I use a CDRWin cuesheet that places a new track every 5 minutes so that's it's easy to skip over segments I don't like.
