You can find some on amazon.com, but for the vast majority of cds are not available.
So you have to order and wait until they arrive to the us or anywhere else. Plus it’s imported product so the price is higher.
So personnaly i’ll prefer to buy directly in Japan on cdjapan.co.jp.
Products are usually available in 2 or 3 days and the shipping cost is not so high with SAL (japanese post) : 500 yen per cd.
Never had any problem with them.
Plus and this is the great advantage, you can listen to the cd on cdjapan.co.jp…
So for all these reasons I’ve decided to choose them as a partner for this site.
Hope you’ll enjoy there services !
