Amazon currently has the Samsung Galaxy S8 available unlocked for just $473.99. That is good for about $100 off of its regular price (which is already down $200 from its original price). This is a really good price for the Galaxy S8, a phone with the same design as the Galaxy S9, and can still stand toe-to-toe with the Galaxy S9.
The Samsung Galaxy S8 sports a 5.8-inch Infinity Display, with a Quad HD+ Super AMOLED Display, the Snapdragon 835 chipset with 4GB of RAM and 64GB of storage. There is a 3000mAh capacity battery inside which is going to keep it going all day long, as well as a 12-megapixel sensor on the back. This is a great camera for a smartphone, and is still one of the best smartphone cameras available - which is really saying something, about 18 months after its initial release. The Samsung Galaxy S8 is a great looking smartphone, and this particular model is unlocked, and it will indeed work with all four US carriers. That means T-Mobile, Sprint, Verizon and AT&T, as well as MVNO's that run on those networks. So this is going to work for virtually everyone out there. Definitely worth checking out right now. This price won't be here for long, so you'll want to grab it before it's gone.
This item is also eligible for Amazon Prime's free shipping. Which includes free two-day shipping, and pretty cheap (usually $3.99) next-day shipping if you need it extra fast. If you are not an Amazon Prime member yet, you can sign up for a free trial of Amazon Prime. You'll get 30 days free (if you're a student, you get 6 months), and then it's $119/year (or $59/year for students). Prime members do get a whole lot more than just free shipping though, so be sure to check out the full benefits.
