Actually a lot of times I go to a yard sale, or thrift store, etc where I find just the disk and would like to have the case, but you really can't find the actual case for the disk... So if you had a disk but no case you'd be in luck ... I actually had my car broken into a while back and the idiot stole my cd case so I had a ton of cd cases and I put some of them on here and they done really well...
