When buying the Galaxy S24 Ultra, the most recent Galaxy phone Amazon will accept for trade-in is the Galaxy S21 Ultra, which it priced at $135. Samsung values the exact same handset at $600. A mind-bogglingly large gap in valuation between the two companies.

Samsung’s 2024 edition of the Galaxy Book4 packs plenty of processing speed and 512GB of memory into a slim laptop that weighs less than 3 pounds. It’s also great for streaming videos and conducting video chats thanks to its generous 14-inch screen, an FHD camera, Dolby Atmos speakers and dual microphones with AI-controlled noise cancellation.
