u can choose whether to have the tracking with it or not. without the tracking it's cheaper but it's an ardous wait. :?
u can ask the owner to unbolt the guitar to save on volumetric weight (assuming u know how to assemble it back or sending the guitar for a setup anyway.) Mine was shipped at USD60, additional USD4 for insurance.
imo for overseas don't get a hardcase.. will make shipping darn ex.
however, if u're concerned about the guy's packing, and especially if it's a set neck, get a hardcase instead. u don't want to risk the intergrity of the neck.
