I still haven't figured this out. I always choose the default option that is automatically checked and says: HIGHLY RECOMMENDED. From there fasttech has sent it Singapore Post four times, and my most recent order went Hong Kong Post.
Shipping Method - shipping methods vs. estimated delivery time

I don't see how I could select anything else.
Only problem is my juice I ordered on the 7th shipped on the 10th sing post by default, and other than one site my tracking hasn't even been accepted. Put in a ticket yesterday voicing my concern, but why choose Singapore by default if days later they are no longer available... And why not send out an email... Hey bob your crap may be there a little longer than expected before it even gets scanned into Singapore post, just a heads up.
