They are indeed much cheaper in Japan. A major cause of the discrepancy is the rapid devaluation of the yen. Tthe Real McCoy's Nagoya (a dealer like Real McCoy's London) used to sell overseas. They even put up an English site. This went very well for a couple of months until Real McCoy's struck some kind of deal with their overseas dealers like Blue and Green etc. and restricted sale of RM products directly from Japan. I guess that's in return for the overseas dealers to open up shops under the Real McCoy's name in various countries. No doubt, Real McCoy's is gaining some publicity and new customers overseas. I hope it goes well for them as they are losing at least one customer, that is me.
