Best Buy has the phone I really want on Sprint for a great deal. Before everyone jumps on the down vote, it does include 18-month bill credits thus it is only good for people who plan to stay with Sprint for that long. It also requires a new line to be opened.
The S8 Active (rugged and giant battery) is 50% off for Sprint, bringing the price down to $17.71/month for 18 months via the Flex Lease, for a total of $318 in payments. This also comes with a $350 Best Buy e-gift card (instead of their normal $350 off Galaxy line of phones), thus in the end this phone should make you $32 for the duration of the 18 months at which point I am informed you will need to send the phone back to Sprint. Your net payments for the device over the 18 months should still be negative, but not really a money maker like I thought.
But again you will be stuck with Sprint for the duration of bill credits - 18 months, and it requires a new line. I am on Verizon, but really want this phone so am out of luck. If this had been available on my carrier, I would have pounced on it immediately.
Good luck. I obviously don't post much / at all, thus please feel free to correct me if I am missing something in this post.
Then Click on the "$17.71 Flex Lease" option box. Here you will see the price of $17.71 / month and the Best Buy e-gift card shows up as included free.
Here is my math:
$17.71 x 18 = $318
-$350 bbuy gift card
-$32 then you can return the phone to Samsung or buy it off for $187.50 for a net cost of $155. Plus the cost of your Sprint line as it is not eligible for free lines.
