The Samsung Galaxy Note8 officially costs $750 in the US, but deals have pushed this price as low as $620. That’s still a bit high, though, an eBay seller with the cheeky name of “never-msrp” is selling new units at $533.
These are unlocked dual SIM phones with Exynos – note that this means only GSM carriers are supported (so no Verizon and Sprint). Only Gold units are left. You can check out the deal here, the seller is located in Houston, Texas.
And while you’re shopping, you may want to check out the Samsung DeX Pad Dock for $67.80 from B&H (normally it's $100). It’s designed for the S9 duo, but will work just fine with the Galaxy Note8 as well.
No Samsung doesn't & hasn't used slaves, you're getting them mixed up with Apple, if you know different then please provide evidence.
You either got a bad one which you should report immediately or you're just lying because I bought from them on Ebay and the device was brand spanking new...
