Hmmm, most all goods shipped out of Bali, going by sea freight end up in Surabaya for final loading and shipping. Many of these trucks going to Surabaya come back to Bali empty which could mean a good deal if you used a freight forwarded located in Bali. I’ve never done this...just speculating. Anyway, a very good, reliable and professional shipper here that we have used for years is CAS Cargo.
You can find information about them, e-mail address, etc at the following web address:
