I've currently got a cruise booked with vacationstogo.com. They had a clearance price (a week if not 3 after the final payment window) which at the time was some $400 or 22% lower than the fares available to almost all other agencies and the cruise line itself. One of the ones that the cruise line dumps inventory through had the teaser online but one couldn't find it when making an online booking. The agent I talked to at VTG managed to find it. He's also quite responsive to requests.
