The Apple Watch Series 4 has been dropping in price consistently after the Series 5 took its place. Even though the Series 4 Watches aren't the latest model, they're still a great choice, especially considering the sale prices on Amazon. If you've been holding out for a Series 4 Watch, it may be prudent to grab one now: Amazon is matching Best Buy's prices on the Apple Watch Series 4 40mm ($299), 44mm ($329) and 44mm with LTE ($399), which are the lowest prices we've seen. That LTE model is particularly notable as it's the more expensive stainless steel model rather than the basic aluminum. These prices almost certainly won't get any lower, and since the Series 4 has been discontinued, they could run out pretty quickly.
