The price on SanDisk's largest microSD card just keeps dropping like a rock. I mean, like... a rock with another heavier rock tied to it or something. After hitting $135 about a week ago, the 200GB microSD card is now $99.99 on Amazon. That's a lot of storage.Not all phones have microSD card slots anymore, but those that do could benefit immensely from 200GB of local storage. You could carry a ton of music or video for offline access or record hours of 4K video. All in this tiny little plastic chip. What a time to be alive.The card is available with Prime shipping and is finally in-line with the cost of other capacities. The 128GB is $45 and the 64GB is $18.Source: Amazon
