A more realistic device to swap, the Samsung Galaxy S21, is only priced at £240 ($304.05). In the U.S., Samsung will pay $650 for the same handset, almost double what U.K. shoppers are being offered.

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.

Now is the best time to pick up one of Samsung’s ultra-premium smartphones, with the Samsung Galaxy S24 Ultra now just $949 at Amazon. That's $350 off! Or if you’d rather something flashier the Galaxy Z Fold 6 is now $1,320 — $500 off the usual price. If you’d rather have a TV, then the 48-inch S90D OLED is now under $1,000.
