I don't think this is possible, but worth a mention (sorry if this was mentioned previously), but I would like to see a system that once a person puts up an item for sale in a bazaar, it'll show up somewhere in this site. Just would make it easier to find items instead of going through (eg. on Kujata) Rolanberry Fields and checking 30 + bazaars for items you may or may not need.
I know that theres a Bazaar Wanted / FS list but it seems that no one really utilizes it. There's probably gonna be an influx of 99999999999999 gil items for sale (which I never understood why players do this) but I still think an automated bazaar list would be helpful, esp. for items that cannot be sold on the AH.
