There is the timeshare store the link is at the top of this page. Also www.dvcbyresale.com which is run by Shontell and you can also try the tug board www.tug2.com which is individual selling..those are the three I can think of...
Although it is offically sold out, you can still get BCV from Disney, as they are getting some points back from people who's credit did not go through.
I just got word from our guide today that our 210 points at BCV went thru at $84 - $10 MB, with a June use year.
So at $74/pt, thats pretty close to the resale prices I have seen, and the points we are giving up for the MB are from June 2003 - June 2004, so on June 2004 we will get the full allocation of points.
It might be worth calling your guide, if you have one, and see what they have available or go on a waitlist.
