where do you get a postal order from
Postal order A postal order is a financial instrument usually intended for sending money through the mail. It is purchased at a post office and is payable at another post office to the named recipient. A small fee for the service, known as poundage, is paid by the purchaser. In the United States, this is known as a postal money order. Postal orders are not legal tender, but a type of promissory note, similar to a cheque.
Postal code A postal code (also known locally in various English-speaking countries throughout the world as a postcode, post code, Eircode, PIN Code or ZIP Code) is a series of letters or digits or both, sometimes including spaces or punctuation, included in a postal address for the purpose of sorting mail.
