That's kinda rude. Assuming SSR, let's see..
100 pts direct from Disney = $112 per point - $19 per point promo = $93 current price, $9300 total (no closing costs - includes one tote bag)
Lowest price 100 point add-on from The Timeshare Store is presently $73 per point, and includes no 2008 points.
So $7300 + ~$500 closing costs = $7800, for a difference of $1500.
Potentially significant, but getting "free" 2008 points and a matching use year from Disney could certainly be worth $1500, along with the convenience of being able to book now.
