MD CC update: Our CC used to have the jewel cases on an endcap of the games isle. Granted they were on the bottom shelf, 20 of them. I bought 1 at the time I saw them displayed (about 5 months ago).
As of this weekend, they are no longer on the endcap. They have been moved into the PS2 shelves. 19 of them, minus my one purchase 5 months ago (if they didn't re-stock).
At least they are mixed in the games, but PS2 isn't exactly prime real estate with 360, PS3, and Wii game sections out.
