TheTechGeek.com has these CD/DVD protective skins on sale, like 65 pecent off.
$19.99 includes S&H costs for 100 or $.20 each.
The reviews on these on the internet all sound promising, but I have never used them personally so do not take this post as a endorsement. I am thinking these should be great for CDs or DVDs you are using all the time like my sons PS2/PS3 game discs.
If anyone has used these before let us all know about your opinion.
