Well, I don't know about the list, but I'll tell you what I did. We are booked for the week after Thanksgiving for a 5 night stay, when I made the reservation I asked about PIN codes and discounts, the CM just told me to keep watch on the site... So I looked around the board for help and found some suggestions..
I went to the main page of the Disney World website and ordered the "Planning DVD" (apparently this gets you into some system). Then I logged into my account on the Disney World site and ordered the "Custom Maps" after that I would just spend about 10-15 minutes on the site every night planning and saving packages. I did this for about a week, and then one night after getting back from eating I had an email from Disney with a PIN Code inside. I called and gave it to the CM, it was applied to my account right away. The code we received was for a discount on the rooms.
35% off Deluxe, 30% off Moderate and 25% off Value.
I hope this helps...
