I basically use 2 different forms of shipping. Please read below;
For shipping charges ranging from US$20 to US$40
I am using DHL or EMS courier service. EMS is a door to door courier service too. They sub-contract their services to USPS, DHL, TNT, UPS and others depending on their agents in the respective country. Generally DHL and EMS take about 4 working days to reach you. Saturday & Sunday are classified as non-working days.
For DHL, you can track it at www.dhl.com.sg
For EMS, you can track it at www.speedpost.com.sg
For shipping charges US$10
For shipping charges US$10 (normally for inexpensive and small items), I will be using registered Airmail to send the parcel worldwide. This is applicable for pens such as Sensa, Retro and etc. In this way, the buyers pay a lower shipping rate for a low cost pens. It takes about 12-14 working days to reach you.
Point to note that the above shipping times is an estimation. It also depends on the speed of customs clearance.
