Which part is confusing ? See if I can help..
Checkout part or registration part ?
Please be informed that the first payment is for the steelbook price, when your items are ready to be ship; they will email you the invoice for the shipping charges. After the second payment of shipping fees completed then they will ship your package.
Their packaging is very good.
1) Registration should not be an issue, so I'll skip that part.
2) After placing your item in the cart, click on the checkout.
3) Confirm your delivery information, if everything in order just click on to continue.
4) Select your payment method, which is Visa only.
5) Confirmation of your order.
6) After you confirm, it would bring you to a secured page to enter your payment info.
Remember to change it to "English" when you enter your info. (Red Box)
You are done and wait for their email for the shipping charges..
Hope this helps.
