I'm not sure if you could do that but you can buy tamashii webshop exclusive stuff from biginjap.com and yokattaweb.jp. However, they usually markup 1000jpy from the price. You can ship the item directly to your home.
On another note, I just ordered a hguc kshatriya from HLJ. Anybody in around Kajang want to buy another stuff so we can split the payment? I have a bad experience with SAL so I'm thinking of using EMS this time.
