Per the Mobile OS Fairness Doctrine, having mentioned the new iPhones, we now have to mention the flagship Android phone with its dual OIS cameras, which, what a coincidence, is also available for pre-order!
If you prefer factory unlocked, with USA warranty and no carrier strings attached, you can get it for $930 in two color options at B&H Photo and Amazon itself.
Samsung’s own store offers it both factory unlocked, and also in six carrier configurations (the Big Four, plus US Cellular and Comcast/Xfinity) for $930. They also have an optional $300 Trade-In Promotion of qualifying/eligible trade-in phones.
UPDATE: if you are a fan of eBay shopping, they have a variety of listings. Keep in mind, eBay is an open marketplace with all kinds of product conditions and authorized dealer status and international models and such, so be sure to scrutinize each listing before buying!
Carriers have a variety of offers with their terms and conditions and restrictions and pitfalls, so be sure to read and understand them before jumping aboard a particular carrier…
There are also some promotions that get you free accessories with early pre-orders. Check each carrier’s various options for details.
AT&T offers a 30-month installment plan with 0% APR on approved credit and such, for $31.67 per month. They have an up to $300 trade-in promotion, fineprint buried at the bottom of that page.
T-Mobile offers an old fashioned “Buy One, Get One FREE” promotion, with their own set of prerequisites and requirements for the promotion.
SPRINT has a “Switch to Sprint” promotion that is $20 per month on the 18-month Sprint FLEX Lease program with monthly bill credits on approved credit, with their prerequisites and restrictions. Note that this is a lease promotion, not a purchase promotion.
Verizon Wireless has a Trade-IN promotion that gets you up to 50% off Galaxy Note 8 with select trade-ins and a monthly payment plan and with other requirements. The 50% off is reserved for ten models (S7*, S8*, iPhone 7*, Pixel XL, etc), while the 35% off is with previous previous generation flagships, and 25% off is three times previous generation models.
