Your P1 can go a long way, at least within the Philippines, as you can now send money locally for up to P1,000.
The Philippine Postal Corp.’s “Piso Padala Promo” has a flat rate of P1 for domestic money transfer amounting up to P1,000 through their local post offices.
Transactions are said to be limited to two send transactions a day per sender-per-beneficiary. Remittances above P1,000 will be charged with regular rates.
