Also see Black Friday sales for the Pixel 3, the iPhone XS and XR, and deals for the excellent OnePlus 6T and top LG models.

In addition to a separate Black Friday offer, Walmart has rolled out savings on unlocked Galaxy S phones. Yes, you have to pay more up front, but an unlocked phone gives you more options when it comes time to choose your carrier, and all you'll need to pay for is the service. The handset will still retain a high level of resale value, and owning it outright means it's easier to carrier-hop as you please.
