The 512GB Samsung P9 Express microSD card, which is made for Nintendo Switch, is currently going at a 25% discount. This brings its price down to just $75, saving you a nice $15. It's the lowest we have seen it drop to since its release, but the offer is only around for a short time. Grab it while it's still live, because once it's gone, we don't expect it to be back at this price anytime soon.
