Woot currently has the Galaxy S8 available for $399 and the Galaxy S8 Plus for $439. These are both certified refurbished models, so these aren't brand new, but are definitely worth picking up at this price. These are also unlocked Verizon models. So there is a Verizon logo on them, but they will work with GSM carriers like AT&T and T-Mobile. So as long as you aren't on Sprint, this will work with your carrier.
The Galaxy S8 and Galaxy S8 Plus were both released last year, with 5.8 and 6.2-inch displays respectively. They are powered by the Snapdragon 835 chipset along with 4GB of RAM and 64GB of on-board storage. Making it a pretty good smartphone, even a year later. These have been updated to Android Oreo as well, so you may have an update waiting to be installed once it arrives on your doorstep. These are only available for a limited time, so you're going to want to pick these up before they are gone. Woot has a very limited quantity and they definitely won't last long. Currently, both the Galaxy S8 and Galaxy S8 Plus are still available in the midnight black and orchid gray colors. So you still have your choice of colors here, but it won't be that way for long.
Woot does offer free shipping, but only for Amazon Prime members. So if you are not an Amazon Prime member, you will need to pay a flat fee for shipping. Although you can also opt to sign up for a free 30-day trial of Amazon Prime and still get free shipping here. So that's a great way to get around it, just remember to cancel your trial before it expires, or you'll be paying $99. Woot does not charge taxes either, which is pretty good for those that want a great deal.
