Which of them provide(s) the best or the fastest delivery? imo CDJapan . Somemore I choose standard airmail & my items come a mere 4 working days after it was shipped out .
CDJapan offers 4 different types of shipping mode & I always choose normal airmail , I don't see the need to pay so much for EMS
also like someone has mentioned before , whatever you buy from CDJapan is counted towards Oricon & so's Amazon Japan .
YesAsia , nope but it's counted towards the charts in Korea
Do they usually ship goods before or on the release date? depends but since I used both YesAsia & CDJapan , I say before .
My copy of BREAKERZ's BIG BANG ! was shipped out 2 days before the actual release date from CDJapan .
Amazon Japan's shipping charges are quite notorious expensive . I usually use it only if I want to get 2nd hand stuff & my Japanese friend will come & help me in this aspect .
YesAsia provides Free Delivery, does the Free Delivery take a long period of time for shipping goods? quite , the fastest my item came from YesAsia was 5 working days
worst was 5 days & beyond
Also I want to say that the way CDJapan packaged the items are fantastic . HMV Japan fold posters & put them inside the huge envelope but for CDJapan from what I was told , they don't do that .
They send everything in a big box , you can see it via
