After a lot of research I settled with shipito.com
pros: will consolidate, take pix, follow orders ie unpack and repack, very cheap, full on-line tracking, reliable, can opt for non-monthly fee
cons: big jump in price between v.cheap shipping options ($6-8 took 2 weeks+) and dearer options (~$40-65+ 3-4 days)
advantages: most US companies will ship road usually free or v.cheap (can add 2-3 days though)
I've used them for a few years, but not a "whole lot". Let me know if you have any questions
Edit: One thing to add. Avoid their California drop-point. They have much tighter TAX rules, and getting exemption can be a pain.
