Replacement Cases - The Clear Part of Them

Every once in a while I go through my cabinet and somehow I manage to find a cracked case for some of my games. I don't know how they get cracked, but that's not the point of the topic...what I'm asking is, is it possible to get the clear part replaced somewhere?

I know you can get replacement cases for CDs at places like HMV (etc) for example, but I was wondering if anyone knew any other places because when I was there, there were no caes with the little circle part at the edge where the cases connect, so they have to be a certain kind of case...

So yeah, ideas / help?

I think you guys mean Jewel Cases.xavierdhjane

Yeah I think that's what they're called.

JCMatrix: I think you misunderstood what I was asking - I already have the cases, I'm just wondering if it's possible to get replacement jewel cases (thanks xavierdhjane).
