Using this Black Friday deal at the official Samsung site, you can either get an unlocked 512GB device for $950 without a trade (a record-low) or a device for as little as $499 with the trade. In the former case, today's discount at Samsung is a whole $100 better than Amazon's cheapest price for a 512GB model, so it's absolutely worth checking out.

Black Friday has begun in earnest at Amazon. Not content with slashing prices in its Prime Day sales, the giant uses Black Friday as an extra chance to offer discounts - and this time, no Prime membership is necessary.
