I have tried CDJapan and YesAsia.

YesAsia has a less price for shipping than CDJapan, I think.
Both are good to order from, honestly.
Just make sure to send a message to YA saying you want bubble wrap + box!
Because sometimes they sent me ONLY box or ONLY bubble wrap ;~;

Like Keiichi said, CDJapan counts for Oricon YA does NOT,
only for Korean CD, it will say under the price.

For me, CDJapan was faster. It got to my place like 2~3 days
after the release date, and I live in Canada!!
It was the same for my friend when I sent her presents.

YesAsia got to my house about.. 7~12 days I think.
I don't usually order from YA unless it's older items
or if I want overseas versions.
