I have been asked in various places about the 4-deck limit and most comments have been complimentary. Honestly I would have sold them much faster without the limit. I'd have to count exactly, but probably 35% of the orders were for the max, so if even a portion of those people would have bought 6 or 8 the deck probably wouldn't have lasted the first hour.
So from a business point of view, I guess that was pretty stupid, but from a collector point of view it seemed like the right thing to do. 
As of this moment, there are just a few bricks left and if some hardcore collector fan here wanted a couple more to store away for a rainy day, I don't think the guy that runs the place would be all that upset. Just sayin...
I don't think that was stupid.
In my opinion that was not only a sign of respect to your clients but also a good marketing move (intended or not).
First, as Don already pointed, the deck is sold out so there was nothing stupid about it.
Second, the imposition of a limit in a 1000 deck run it's really an honest way to try to guarantee that everybody has a chance on the deck.
Third, even with a limit, it's always possible to have multiple accounts.
And fourth, I really think that the limit helped you to sell more decks to each person. As you pointed out, 35% purchased 4 decks. If you had no limit,some people could buy more, it's true. But, now I'm talking by my personal experience, if there was no limit, I would probably buy 3 decks because they were not cheap. Let's be honnest, 80 dollars by 4 decks was above my limit. But with the (deserved) expectations generated in collectors, the first impulse it's to buy the max. With no limit It wouldn't be a surprise if a great percentage would only buy 3 or 2 decks.
So, don't feel bad with the limit.
