Back in August, I needed to reinstall OS X, and when I went to do it, I discovered I had two Disc 1s. I contacted AppleCare, and I got them to send me some replacement DVDs. Something got screwed up, and nothing was mailed. I got on their case, and several weeks later, it was finally mailed and arrived. I reinstalled OS X, and that was that. Today, I got a package from AppleCare. My original replacement DVDs just arrived today. Truly bizzare.
