Last year there were huge delays for the registration and it did not start until 19 May (for people attending).
They planned for people not attending to register the week later (but it took until 3 June US date).
They charged my credit card the same day (4 June AUS date).
You will need your credit card as they have this rule if you've never ordered anything from the Club before:
Upon your first order, you will need to fax us a copy of your credit card, front and back as well as photo identification, which shows your signature to 817-448-9843. If a credit card transaction is made through our site without the fax confirmation of your identity, we reserve the right to CANCEL THE ORDER less the online service fee and $25 per package cancellation fee.
Yes, the Iacon/Non-attendee pack gets you the box set only sent to you a month or two after BotCon.
You can't order the other exclusives. You have to be there to buy them, get someone there to try and buy them for you, or ebay them
