Although mobile devices seem to be coming with increased levels of internal storage nowadays, having enough can still be an issue. Thanks to the increase in music, movies and apps that we carry on our devices, storage builds and fills up quickly. Luckily though, external SD cards are available. As such, whenever good SD cards become available at a reduced cost, they are normally worth picking up at least one, if not more. Well, Amazon currently has a deal going on a Samsung 64GB memory card which means you can pick one up for only $20.98. This is an EVO 64GB microSD Card and comes with the adapter for use with standard SD devices. If you are interested in grabbing a few microSD cards then now is the time.
