But Disney knows there are enough fans out there willing to throw cash at anything. When you make it limited, they'll throw more and much quicker. This is a prime example of that.
Personally, I consider a money-grab charging a family of four $600 to spend three extra hours in the Magic Kingdom after closing it two hours earlier for everyone else (but not really since they aren't saying how many people they are selling this same experience to).
When you consider the amount of paid labor involved in what they produced for this that we so far know about - the going rates for that kind of labor - the management of it, the degree of planning, etc. it appears that something else must be going on with this. Now, if they had limited it to say 50,000, it still would have sold out, at least in a few days and then you'd have had a point because their costs would have been much, much, lower per sale.
At 999, they're looking at less than $200k in total sales. Even if that was nothing but pure profit, it wouldn't be enough to move the bar that much for a company like Disney but hey, they sometimes do it with a pin or a t-shirt that they'll sell for $15-$50.
Within that $200k though, they are paying for whoever mapped the whole offering out, App development, web development (QA testing for both) - lots of custom or customized artwork, lots of graphic design and page layout, paper engineering, exotic printing processes, custom product design, copywriting, limited run production of physical merchandise, etc.
There are enough disciplines at work here that it had to be done by more than just a tiny team of people. If you consider all that, it can't add up to much for them which is why I'd be surprised if this wasn't a live test of some sort of concept in development.
Maybe you would have preferred whatever $66.66 could have gotten you in merch from Disney that was limited to an edition size of 999. Looking at Art of Disney pricing, I'm guessing that might have been a few pins, maybe?
Regardless, if it's not your thing, that's cool. A lot of people would rather buy an awesome home entertainment system than pay for a trip to Disney with their family (regardless of the current state of the parks).
To each, their own.
I just don't want you to have the impression that Disney's making hand-over-fist money with this. They're not.
