B&H Photo is currently selling Samsung's super-fast, EVO+ 128GB Micro SD Card for just $59.99. That takes $40 off of its regular price of $99.99. This is not an all time low, but it is within $5 of it, which was last weekend during Black Friday. So if you did miss that sale, this is a great one to take advantage of now.
This micro SD card from Samsung is part of its EVO+ lineup. Which is a class 10 card, and has read speeds of 100MB/s and write speeds of around 90MB/s. That's pretty fast, and actually the fastest for micro SD cards currently. What this means, for average users, is that it will be fast enough to write 4K video to the SD card without making the camera on your smartphone wait to start recording again. It also means that whatever is stored on your SD card, other media, apps, etc., a bit faster to load. Which is definitely important. It'll also be pretty good for Adoptable Storage, on Android devices. Now this comes with an SD card adapter, so you could also use it in a camera or a GoPro (which most use a micro SD card anyways).
At B&H Photo, you do get free expedited shipping, and if you purchase before 4PM EST today, it will ship from its New York City warehouse today. There's no taxes being collected unless you reside in the state of New York or New Jersey.
