I still don't understand why there is a surcharge on mixed bricks. It costs $4 more to take 6 decks from "Pile A" & "Pile B" as opposed to taking 12 decks from "Pile A" or "Pile B". Really? I have no complaints about the price of the deck, and like what Fes said, some of the deals here are probably the best ever. Just the surcharge.... 
I may be wrong, but I think the cards come in sealed bricks from USPCC
It would seem that they're charging two people four dollars each for an employee to open four bricks and make them all contain six of each type. It's about a half-minute's work, a minute if you take your time.
I've never seen any other company do that. Still, it is cheaper than any of the lower tiers on a per-deck basis.
I'm also not liking the fact that KS now allows people to break out the shipping costs from the prices listed in the tiers. In essence, while there was once an advantage over retail prices in that the KS price included shipping for domestic orders, that advantage has been ceded and the pricing is absolutely no different to retail with shipping costs charged separately. It reminds me of how I felt when I saw a major pizza chain offer all kinds of discounts for ordering online - then charged a $2.50 delivery free while all the mom-and-pop pizza joints deliver for free. OK, it's a terrible analogy, but I'm talking about a feeling more than an event - seeing that there was a catch behind the pricing, a change from the expected norm, and how that left me feeling.
But that's not the fault of GW in this case. It's KS as a whole, and as much as I miss that edge feeling, it does allow one to carefully compare real pricing for both the product and the shipping. I'd feel better about it if creators listed that bump for shipping in the tier itself, but that would make them appear less attractive.
I plan on backing for a four-deck set, two of each. I like the design and the price isn't bad - it breaks down to $9 a pack with shipping, a veritable bargain compared to some projects.
