No credit card? I advise you to order paymaya card. Try to search on it. No registration required. Just order on their website and pay 150php when the card delivered.Then follow instructions how to register it under your name.
Then create an account in paypal, link your newly registered paymaya card.
Im using it and can purchase items i want online.
Just make sure that you have enough balance on it before purchasing anything.
You can reload it even in 7/11 kiosk, sm, rob, ministop,
