About a year ago, every AOL disc that came in the mail was in a DVD case. Those stickers on the case were a bitch to get off, though.
Now all the AOL discs I get come in metal tins. I use the discs as drink coasters, but that's another story. :lol:
Anyways, eBay is your best bet. Sony should do what Nintendo does and sell the cases on their website.
