They actually don't sell very many boards out of their factory. If any really. Their splitboards were the made to order thing at the factory this year. Next season splitboards will be at their retailers. They certainly don't keep boards in stock to sell on their website.
Anyway, Neversummer keeps track of their dealer inventories. When you order through their website, they get the stuff from the nearest dealer in their network who has the goods you want. Sounds like Salt Lake was the spot for this one.
It's actually a pretty sweet thing that they do this. Shipping costs for you aside...
