First time sending to USA with small package post with track and trace. The postage fee is 50% less as compared to parcel post for same weight. Extra work needed due I had to custom made the box to fit 250mm x 200mm x100mm size restriction and weight not more than 2 kg.
So for countries like USA, Great Britain & Nothern Ireland, Irish Republic, Canada etc. It will cost RM 75.00 to send, that is about USD 25.00 for each siphon.
