Meh, Osaka still has quite a bit of haggling opportunities for those who can. It is an old merchant center after all.

@Suspectimus Prime - if you're in Osaka over the weekend PM me and I'll try to make time to give you a TF shop tour if you want. Weekdays I have work and I'm a half-hour away from the city proper, so getting to the TF shops in time for them to still be open is tricky.
If not, the ever-awesome heroic_decepticon has a handy map or three that might help.
