Our house in Manila is just 5-10 mins away from the main office of Philpost. Mind you it's sometimes still a hassle picking up parcels from post office. If I go there at 9am after my work (I used to work on nightshifts), I often wait for 30 mins or so for the employees to get in for work! And if I go there before I go to work, expect that I'd be late for work because of plenty of people picking up their parcels to make it on their cut off time (5pm).
But what I can recommend is their international courier service. I used Philpost to send my stuffs from the Philippines to UK. It cost me around Php12K+ for a 27kg parcel and it arrived so quick here in the UK (barely 2 weeks). It was way cheaper than what DHL, Fedex, LBC, etc. quoted me (Php15K+ for just around 10kg parcel).
