Amazon has a boat load of microSD cards on sale today. There are two different sales going on. We've got a number of Transcend microSD cards on sale as well as Sandisk. So that you can have your pick at either brand. We're seeing 16GB, 32GB and 64GB variations on sale, as well as some regular sized SD cards, for those that still have a need for those. Sandisk has their Extreme Plus microSD cards on sale which deliver up to 80mbps write speed. Which is more than enough for most smartphones these days, but with 4K beginning to pop up more and more it seems that we'll really be using that 80mbps write speed on theses SD cards now. You can check out both brands of SD cards that are on sale from the links below.
