I'll just copy and paste from my post on the original thread....
It looks like most of the rates are valid until mid September. There are a few blackout periods (where they are either at or near capacity in the height of summer).
I believe they only have a limited supply of rooms per resort and it states in bold that this is a "time limited" offer due to expire at any time.
We wanted POR, but they have none of the discounted rooms for our dates in Sept. but POFQ had them, so for a savings of $400 we had no problem switching to French Quarter (we love both resorts anyway).
Just looking at the overall listings of rooms they have available, here are some sample rates at the various WDW resorts:
WL $149
WL Villas $205
BC $204
BC Villas $205
YC $204
BW $204
OKW $183
AKL $149
AKL Villas $254
Poly $208
Contemporary $170
Grand Floridian $254
Saratoga $183
CBR $75
POFQ $74
All Stars $59
POP $59
Swan, Dolphin, POR, Coronado, and Fort Wilderness all seem to be at regular price.
**Keeping in mind that I am looking at the CDN rates on travelocity.ca so US rates are likely to be a bit cheaper**
