This is very correct! Do keep in mind that the sales people will tell you that such n' such resort is sold out that you may be interested in. Keep at them for the number of points you want. They always have points that Disney did ROFR on in a resale deal. We got 200 points in 2011 for VWL for less than $100 per point when they insisted it was sold out.
The points end earlier than if we bought add ons to our existing contracts. We don't care about that. We will be dead and gone before that year rolls around anyways.
Also; some people keep forgetting this one point. Resale
DVC points purchased after (I think) April 2010 can no longer be used for transfer to
DCL or RCI or Adventures By Disney. ONLY points purchased direct from Disney or Add Ons (after that date) to existing contacts can be used for DCL or RCI or Adventures By Disney.
The CMs see on their computer screen a big red box stating that "This Contract Ineligible for Transfers".
