Which one provides the fastest delivery? YesAsia, CDJapan or Amazon.co.jp?

My expierence with YesAsia:

-When I order something it usually takes a week or a 1½ week before I have it the product. (Free Delivery, but it also depends on the country you live in.)
-YesAsia products are always shipped in boxes or carton bags (from what I know). And the products are well protected by bubble plastic.
-I believe that if you preorder from YesAsia they ship it the day before the official release date or on the date of official release.
