both caribe and metro do deliveries, to be picked up from their locations. we used to send paperwork to SD regularly and a package was about 100 pesos.
i go every week 1 or 2 times from santiago where i work to visit my familiy in SDQ. if you need some deliveries PM me. Going with caribetour or transporte espinal and from there to SDQ Oeste. If its on the way i can do you some favors!
