I'd offer mine, but my rabbit thought it was a chew toy. I left it on the floor after trying several times to get the game to work. Bought it PP'd from EB, and the damn thing just would not work. Ran through HDA to see if that would help, and it loaded, saved the game fine, but I can't get the game disc itself to run at all. Frustrated, left it on the floor while I grabbed the phone and called the store. My rabbit, in the meantime, thought it was a treat. Got back and it was ALL
ed up. Got to the store, and wouldn't you know, they don't cover animal damages. Last time I went to that one. Mgr at the other store was nicer about it, but still couldn't do anything about it since there are no replacements, and their coverage doesn't cover that. Did point me in the direction of many 'consolation' games, though. However, my Disgaea is a wall decoration, sadly.
This will be your best bet, for now:

Also, call up your local EB Games. If they have their new VPN system installed, they can search the inventories of all stores in their districts, and, if they like your money, get a copy to you. I also believe gamestop's site has an item-to-store locator.
