Preguntas sobre ejemplos de oraciones con, y la definición y uso de "Po"

A: PO Boxes are locked boxes in post offices with the purpose of getting mail delivered to them. They are often smaller than regular mail boxes at people’s houses. People will use them if they do not want to give out their home address or, perhaps, if they do not have a mailing address. They usually cost money. Some companies even use PO Boxes.

Regarding PO# 170077, I will ship it out on 5/9.

The last sentence, threw me off the conversation because normally you cannot answer for the customer.

I'd say:
You also have an option to ship it out individually as well. Will that be okay with you?

A: I'd just cut out the "for" preposition right before them because as far as I know,you reconcile with someone or just the verb.
I'd say it like this: I think it's easy for them (BEFORE the main verb) to reconcile so, they need the PO number on the invoice. Got it?
