E-Bay its your only chance unless EA decide to rererelese the KS, but why sould they do that?
I am starting to think that EA is making KS and puting the games on sale in E-Bay, so they can get more Ca$h.
Check and see if there's a software store in your area that sells used software. I got WC4 for only $10 at a place like that a few years ago. If it helps, the store was called Software, Etc.
