TVshowsOnDVD are reporting that
Girlfriends: The Sixth Season will be hitting stores on February 24, 2009!
Woo hoo! This is the last season for Toni, and also the last season I don't own yet (since Seasons 7 and 8 are on iTunes), so I am super-pumped for this release.
They also hinted that the whole series should be released by the end of 2009. Great!
