As I troll through the hundreds of bazaars in lower jueno and port jueno and on the AH website, where i have to do /sea all, to see if they're online and send tells and hope they speak my language, I am reminded of a free to play game called rappelz. There existed in this game a 'shop zone' specifically designed for what we consider bazaaring. Your character, sitting all night/day, trying to sell something. Puts everyone trying to sell something in the same place.

New zone proposal, like the mog garden, can be reached from the mog house. You can go to the "Exchange" where all characters can go to buy things that are un-auctionable, and where players can put themselves for the sole reason of selling their wares. Then you don't have to hunt for people all over the world. I can be a leafallia sized area or something, doesn't have to be fancy.
