So they do ship direct now?
No, they still only ship to Japan, but i've been making use of JapanToDoor.com as a relatively cheap forwarding service. Basically i log on to Cave Shop, buy my items, ship them to my JTD address and when they arrive JTD ships them to me. There's usually a $5 USD invoicing fee and a handling charge based on weight. So far it's added like $20 at most to my shipping. It's a huge help when buying stuff off Amazon that's got a major sale (like 60%+ off).
This order was just expensive due to the size of the posters. Most of the cost was EMS shipping. In this case:
3200 JPY shipping exchanged to $40.15 + $5 Invoicing + $12.55 handling.
