For ADD-ONS only, you will get developer points plus money off per point. For AKV, you will receive $8 off per point and for SSR $10 (I think the regular price for both are now $104/pt). Developer points are rewarded at three levels:
110 points + discount + 110 developer points
160 points + discount + 240 developer points
210 points + discount + 420 developer points
In other words, 110 to 159 points get matching developer points, 160 to 209 get 1.5 times, and 210 and above get double developer points. If your UY is Sept, Oct, Nov or Dec., you get 2006 points with MFs prorated.
Offer ends August 31st. You must visit in person. You cannot add-on over the phone. Banking deadlines are waived but you must use the developer points within 12 months of closing.
