Due to an ongoing lawsuit over its blood oxygen sensing system, Apple has officially stopped selling the Series 9 in the United States. For the moment, you can still find this advanced smartwatch in stock at a handful of retailers like Amazon, Walmart and Best Buy, but due to availability issues, there aren’t any discounts. If you’re looking to purchase one, we’d recommend getting your order in soon, as there’s no telling if or when it will be officially rereleased.
