When I was booking my trip last March, my PIN wasn't getting me anything I could use for our week. I asked if there were any other 'deals' right now at Disney, and the CM said he wasn't allowed to tell me about any, or direct me in any direction to get one. He said if I came across the code (three letter code) then he could try to search for something using that offer. I totally understand why Disney doesn't want their CM's to do this... it's like giving away free money to people who are calling and planning to book rack rate.
Luckily, I found a few deals, kept trying (still with no luck), and finally scored with my original PIN 3 days later.
Basically, go to Mousesavers.com and find all the codes that are public offers right now. Call back, and see what you can get applied. I think this is what he meant when he said "they are online".
