Err... What do you mean by that? If compared to CDJapan the AT2007 is cheaper at YA:
YesAsia - 4735¥(with "free shipping")
CDJapan - 4800¥(without the add of the shipping costs)
However if you compare to the likes of HMV then I understand:
HMV Japan -
3982¥(without the add of the shipping costs)
with the shipping costs this too exceeds the price of "free shipping" at YA though.
