I just edited my post. There is no OTO as this is what i found from main wso page
8) Does this Course have a One Time Offer (OTO)?
There are no OTO but UPGRADES - There are 2 UPGRADES available to the buyers of The Adsense Dragon. I can assure you that it's 100% high-octane value at a screaming discount and therefore very difficult to resist (you've been warned). The UPGRADES are in NO WAY necessary to make this product work exactly the way advertised here. Rest assured - you will still be able to become an AdSensible guy (as I would cheesily say), even without the OTOs. (thanks Kevin Rogers)
