Takuhi said:Sorry. As far as I know, the train station (I think? Or somewhere else in Gohtza) in disc 3 is the last opportunity to buy them. Ever. They do not exist as treasures anywhere in the game, unfortunately.
Everyone else, buy 'em while you can!
That's not true.
I just got to Gohtza and I already have them (ie - didn't buy them at the shop). I don't remember where exactly I got them though.
But there has to be another location earlier in the game....
