This article is from the Charmed FAQ, by Colin A. McGregor (firstname.lastname@example.org) with numerous contributions by others.
The First season of Charmed has been released on DVD. For details have a
look at: http://dvd-archives.com/. Note that I gather this site is NOT
offering DVDs sanctioned by the studio, so those who are concerned about
the legalities should probably stay away. As well, there have been some
reports of this firm not shipping the DVDs as promised, so be careful.
