I would like to send small packages to a friend in Puerto Plata. Is the Dominican Mail/Postal Service reliable? She has a Postal Office close by in her neighborhood of Montellano. FedEx, UPS and DHL do not seem to service her area. She seems to believe that the post office in her neighborhood will receive the packages and call her for pick-up. I just want to send her clothing, shoes and vitamins. I know that there are dozens of shipping companies here in New York but they seem to specialize is shipments of big boxes, vats and large containers. Any ideas?
