I agree, Amazon is fast in an insane way. It takes 3 days from Japan to Argentina (bear in mind that flights usually go Japan-USA-South America). CDJapan uses EMS shipping and that takes 1 week or even more to reach here, but 1 or more days are spent in Customs.
About freebies, I heard that people got copies from CDJapan without extras, so HMV must be the only option.
