Forms of payment accepted on The Postal Store®. VISA®; MasterCard®; Discover®; American Express™.Apple Pay defaults to credit, so you're not able to purchase a money order with it. Find out about financing, payment methods, refunds, promotions, rebates, coupons, VAT and invoicing with the payments help section. Write your address in the purchaser section. Include your account number if you're paying a bill. Decide on the money order amount. But there is ways around it. Yes, you can buy a money order with Apple Pay, but it largely depends on the location and the payment options the merchant accepts. For a money order, you'll need to provide your first and last name, your birth date (both written on the front of the order), and the correct payee details.
