That's the thing really... if you have no interest in any of the toys and the boxsets sell out, you will be guaranteed to be able to resell yours at the full ($409) price you paid (and more), and end up getting all-access to the convention for free - including the extra day and evening events that are not available to walk-ins, who would end up paying more than you did just to end up with limited access. And with the bonus Attendee figure and the Club Membership toy that you'll get next year to sell on top of the Boxset, you will actually be making money from attending.

And even if you have to discount your boxset by a little to get it sold (if it was a failed year and the Club has heaps of boxsets left unsold), you should still be able to sell it off for no more than $100 off, and still make up the difference with the bonus Attendee toy and Membership toy... and even if all that doesn't sell to make up the difference of the boxset, you would still be paying less than a walk-in would for both "walk-in days" (Saturday & Sunday), plus you have access to the extra day (Friday) and all the evening events.

So if you have the money on-hand to afford it (because you won't get it back for a couple months), and you have no interest in any of the FunPub toys, there is a financial benefit to registering over being a walk-in... which could make you a fair bit of money if it is a popular year (or at the very least if it isn't a popular year, it will cover your Registration cost and you'd spend the entire 3 days there for free).
