After i read this thread , is that meaning Custom charge is base on luck? is they charge you sesuka hati?

I bought a USD 35 item from blizzard USA, shipping is USD 18.

At malaysia, they charge my item

USD 35 + RM 480 freight fees....mean my item total suddenly boost to RM 630

ok fine, the most sucking part is, they charge me 30% fee + 6% GST, and i dunno WTF is the 30% fees for!?

My item is 2.2KG
