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.

The sale is available now and runs through Nov. 26.
