Thanks I will use credit card.You can use a CC and keep the old address on file. Make sure you don't change address on credit card and have electronic statements ON so nothing goes to your old address. I did the same and CC was charged successfully. Then I changed my address on CC. Not the best way but its possible. The problem with money order or certified check is there is not way to know if FBI is processing or not. With a CC you know instantly when your CC is charged.
Last question should I send single credit card for me and spouse and mention
2X 18$
