Moving and ordering a Gold Card can be tricky. First thing to remember is keep you current address up to date hourly if possible. It appears that the shipping address is taken at the time the order is shipped not at the time the order is placed. This means the moment you move change your address because you will never know when they will choose to ship your order. I forgot to do that until i got the email saying they were shipping it to my old address.
Which brings me to the other thing to remember. Which is that your Gold Card will be shipped standard post. I'm not sure how it works in other countries but in the USA you can have your mail forwarded free of charge. If you can have your mail forwarded then you will have no problems, in 6 weeks or less your card will arrive.
Also key thing to note. When you get your card don't go generating random pins like i did else you will have to re-sync your card
Hope this helps with the anxiety.
