I would recommend you check out Club Correos and other mail forwarders. They give you a PO box in Miami or somewhere similar. Then you pay them a fairly high price, like five or six dollars a pound, to ship it to you and take care of customs issues. The trouble I have had is they require an invoice in each package, but for reasons beyond my understanding, they are often not able to handle the submitted invoice in their computer system. Then I have had to scramble to obtain copies and put then in a format acceptable to their computer. I would only use them for items you NEED but cannot find acceptable substitutes for in Ecuador.
