The only promotions mentioned in the webcast involve Animal Kingdom Villas and Aulani. For purchases of 160 - 319 points at either resort, the member receives a $500 Disney gift card and either four WDW 5-Day Parkhoppers or two Disneyland Resort Premium Annual Passports. In addition, if you buy 160 points you'll receive a $1,920 credit toward the purchase. I assume the credit, which is the equivalent of $12 a point, increases if you buy more than 160 points.
For purchases of 320 points or more at AKV or Aulani, members will get the same Park tickets and credit as above, but the amount of the Disney Gift Card increases from $500 to $1,000.
These special webcast incentives are available until September 7, 2013.
