As part of the ongoing Prime Day sale, Amazon is now offering Samsung’s 256GB P9 Express microSD card for $39.99 shipped. It originally launched at $55 before climbing as high as $80 earlier this year. Today’s 50% Prime Day offer takes $40 off that usual going rate to mark one of the steepest price drops we have tracked for it. While it did briefly dip to $31.50 before the price hike, this is the best price we have tracked since then. Samsung also offers a 512GB version for anyone who needs more space, but that variant is fetching a much higher $189 price right now. Head below for more details.

Samsung’s P9 Express is one of the brand’s latest high-speed microSD cards, with transfer speeds of up to 800MB/s for faster file transfers and game loads. It comes in 256GB and 512GB capacities and supports both UHS-I and UHS-II devices, making it a flexible option that works across devices like cameras, handhelds, and other gear. Samsung also includes protection against water, temperature extremes, magnets, and other everyday hazards, alongside a three-year limited warranty. It works with Samsung Magician as well, giving you access to authenticity checks, performance monitoring, and drive-health tools.
