^ HMV Japan's shipping is not cheap and they often give you another shipping quote when the goods are ready to ship, usually at a much higher cost.
Charoite is right about HMV's packaging being sucked.
My opinion, if you are just buying CDs and DVDs, use Club Japan and take advantage of their free shipping.
On books/PB, gather all your items and use Amazon Japan, shipping is not cheap but is reasonable if you order more than one item.
Example, the shipping is double with HMV on calendars but with Amazon Japan, the first one is 1500Y and 300Y on the second one.
