Dom Perignon questions

[schleppo]

I have a friend getting married this year and I wanted to get a bottle of Dom Perignon as a wedding gift that was bottled the month and year he met his wife-to-be (September 1995). Not knowing much about wines, I would think that wineries bottle around the same time every year based on crop maturity, but I don't know. So, my questions are these:
1. Does a bottle of Dom Perignon bottled September 1995 exist?
2. If so, what do I do/where do I go to find one?
3. How much should I expect to pay?

Thanks in advance to any of you who reply and I hope if I've spoken in a particularly "newbie" manner, you didn't laugh too hard! *;^)
