WHERE VACATIONS START!
There is a guy in Bocas del Toro who ships containers both ways and accepts shipments of various sizes for consolidatdion into the containers. I have seen ads for the service in one or more of the free papers.
I may have saved an ad and will go through all of my very neat files (Ha!) and see if I can find it.
Try Panalpina. A worldwide shipping agency. They are in Colon (search Google). They arrange everything incl. consolidated container shipments, customs paperwork etc.
B&B Moving here in Boquete does these kinds of shipments all of the time. They're referred to as Less Than Container Loads (LCLs). They place your item on a single pallet (or more if needed) or build a custom crate for it, shrink wrap it, and then ship it in a container shared with other LCLs. They do weekly shipments to the states.
Thank you everybody. Someone told me about another person who does consolidated container loads. He is Steve Gibson 6900-0764.
