Hi,
only subscribed users can use their money, so you have to buy subscription, but it is possible with your A$. You have to buy at least a 3 days long subscription, it allows you to use the bought items. If you take them on, you can wear them after your short subscription has already ended (just don't take them off…). The subscription has additional cost, it is important when you want to use your A$ received as gift. We will add an explanation to the gifting procedure, sorry for the inconvenience.
Regards,
tom
