My guess would be that FitEar aren't able to keep up with demand. They literally hand-make every one of these in Chiba/Ginza, so it takes time, effort, and more patience from potential buyers than other earphone brands. In some ways, I'm surprised FitEar have decided to have so many vendors outside Japan. Again, still looking for someone to buy my SM3 (not music) so that I can get a slice of the 111.
Seems the TO GO! 111 may be out of stock, too --- it's not currently showing on the FUJIYA AVIC online shop --the only online shop that seemed to carry the TG! 111s-- so, obviously, PriceJapan isn't showing them, either.
