The California State University system contracted with PeopleSoft to consolidate their various non integrated systems back in 2003. Initial costs were supposed to be 350 million, but instead ballooned to over 700 million. We still don't use the full functionality of the suite, even though it's all been payed for.

And it's the absolutely worst system ever, a complete pain in the ass in every way. If you've never touched PeopleSoft, they not only spent hundreds of millions on a system, but on a system that sucks away years from your life-force.
