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.

Samsung is rolling out the most compelling promotions of the year for Black Friday and the Galaxy S24 Ultra is at the center of it all. On the official store, if you purchase the 512GB version of the Galaxy S24 Ultra, you will only pay the price of the 256GB model ( “double the storage on us”) and this alone saves you $120.
