Wow that is super informative, thank you so much for your help, I can't begin to express how grateful I am to finally receive such a rock solid answer and the reasoning behind it. She has had things delivered to her including mail from me. I spoke to someone else who went through the process that is also from Pasig, she said that for province they put metro manila. Everything I've mailed to her and flowers I've had delivered to her were successful using metro manila as the province when province was asked for. Again it was so nice to receive this reply, thank you!
