If your mailing address is a Dumaguete city address, you can use USPS international priority mailing services ( and registered etc I am assuming)etc-- I just recently rented a PO Box @ the PhilPost by Quezon Park (Catalina Street) and haven't recvd any rush/registered packages, but did get my insurance ID card in a reasonable time, and noted it was standard international airmail @ $1.15 postage--
