Maybe the item you ordered can't be shipped outside the US. Try other items ^^

Well..still depends..read the description whether is it only for US customers or what..
I've bought a DVD from there without any problems~

For example..the Hasbro Transformers Ultimate Bumblebee Figure from AMAZON.

What's the shipping method? You need to visit the customs at KLIA.

I'm not sure what shipping method is that..but usually what you have to do is print out an invoice by Amazon, drive to KLIA and be prepared to pay tax.

You can try to negotiate with the officers to reduce your tax.

However if you're shipping method is EMS or SpeedPost, you'll be exempted from tax if the total cost of the item you bought is less than RM500 (total cost = item cost + shipping cost).

Btw, how did you receive the letter? Via normal post or PosLaju?

Oh..then you'll need to pay tax 

nowaday most domestic US shipping is free!
