Ordered the new UN architecture series offering. Ordered from Amazon. I'm Amazon prime. Order yesterday, received today in less that 24 hours. I'm Amazon prime, I selected free two day shipping. Since I live in a large metro area and they have an 'end of runway' operation in Memphis, I got overnight service for free.
Interesting, but when I first looked on the Lego site early yesterday, they showed the UN as out of stock. Changed a few hours later to available, but by then I'd ordered though Amazon. Since my order through lego would have been under $75, I would have paid for shipping plus it would have taken a day or two longer in transit.
