Intel is usually pretty good about making new processors available in quantities to satisfy demand, but for the time being, that does not seem to be the case with Coffee Lake, at least for some of the higher end SKUs. For example, its flagship Coffee Lake chip, Core i7-8700K, is sold out pretty much across the board.

We are sure there are vendors out there selling limited stock at a price hike, but in our glance around the web, the Core i7-8700K is currently MIA. Newegg does not have an stock available, and neither does the Amazon. Over at B&H Photo, you can preorder the top-end Coffee Lake part, but there is no indication of when it will ship other than it's "coming soon."
