Well, Here's my Idea, and I'm surprised I can't find it on the net.
Everyone is farmilliar with "ronund-with-hole-in-middle" CD labels
that you can print on and put on your burned CD's...
These are great for obvious reasons...
The main thing that I like about them is that they protect the top of the CD.

Now why is it that I cannot buy clear plastic ones for my store bought CD's ?
I can get clear plastic mailing labels that I can print on... from Avery.
Why not for CD's ?
It would just be sorta like CD shaped pieces of Scotch Tape.
I think this product would KILL in the marketplace... Easily worth $1 a disc.
Anyone ever seen this anywhere.
Now that I say it, I bet you guys post a bunch of links to places I can buy it already,
Either that or Avery starts making them tomorrow.
I've had a few decent ideas recently,
only to see them implemented in mass, almost immediately.
(with the exception of one idea for a "beer fridge" that maybe I'll go into later under "Off-Topic")
Timimg is everything I guess.
