Low-cost China -> US shipping vendors?

[Daniel Clark]

Does anyone know of good low-cost China -> US shipping vendors?

I'm thinking probably something via boats / partial containers,
although I'd also be interested in any airmail vendors with costs
lower than EMS.

May be useful for shipping medium-large numbers of Ben Nanonotes,
although at the moment I'm looking for shipping small-medium
quantities of (of course heavier/bigger) Lemote Yeeloongs.

Thanks for any leads,
