Looking at vPost, I don't think I need the total service like this. Is there a way I can separately pay the GST on the package, say if I get it shipped DHL, or FEDEX to me?
GST is on anything >400 SGD. For some weird reason, even with shipping and GST, sometimes it's still cheaper to get from the US (or abroad for that matter.
DHL , FedEX I think will handle the GST then just charge you later. SingPost (if your deliveries will use USPTO) will NOT give you your package until you've paid GST. You can either go to Paya Lebar and pay in SingPost (Customs, actually) there or you can tell SingPost to authorize the post man to receive GST payment.
If you're going through SingPost, normally, they'd post you a notice about the GST. You can skip the wait for that mail by tracking your item and when it arrives in Singapore, then call SingPost telling them you're expecting something and would like to pay GST upon delivery (involves emailing them a form; the guy on the other line can walk you through the procedure). That should quicken things up.
BTW, check with US postal services; I read somewhere that they would no longer carry lithium ion batteries via air. Haven't seen a follow up on that.
