>>1026964740700 yen are roughly 300 bucks, not 400.
Most transfroming SoCs were already 230+ bucks years ago (like GaoGaiGar), so it really doesn't surprise me at all taking into account how other lines have skyrocketed in prices as of late. If anything I was expecting it to be more expensive.
I ordered it for a bit less than 320 dollars with taxes and shipping included, so that's a pretty good deal for someone living in Europe. Customs would have obliterated my wallet otherwise.
