Final answer:
No, the .89 cent money order fee is usually not included in the amount written on the money order but is paid separately. The written amount should be the exact amount you want the recipient to receive. Keep your receipt for proof of purchase.
Step-by-step explanation:
When completing a money order using a money order machine, you typically should not include the money order fee in the amount you are sending. The fee for the service, such as the .89 cent fee mentioned, is usually paid separately and is the cost for processing the money order. The amount you write on the money order should correspond to the exact amount you intend the recipient to receive. The machine will then add the fee on top of this amount as the total you need to pay.
It's important to clarify the total costs with the institution providing the service, as practices may vary. However, generally, the fee is paid separately and not included in the face value of the money order itself.
Always remember to keep your receipt as proof of purchase, which can be useful if the money order is lost or stolen.
