If you need an absolutely massive amount of storage for your Android phone or tablet, you might want to mosey on over to Amazon before the day is out. The retailer is offering SanDisk's Ultra MicroSDXC card in its highest capacity, 200 glorious gigabytes, for just $79.99. That's an amazing $170 off of the suggested retail price. According to the product listing, that price is available for only the rest of the day (Saturday, December 26th) and it ends at approximately 2AM Pacific time.

This is the cheapest we've seen this top-of-the-line MicroSD card yet - before today, the lowest price was $100, also at Amazon. This is a Class 10 card with a claimed transfer speed of up to 90MBps, so in addition to anything you'd like to add to your phone (including Android Marshmallow's adoptable storage), it should work just fine for high-end still and video cameras as well. As with most Amazon deals, this one is eligible for free two-day shipping with Prime, but even regular customers should qualify for free standard shipping with the purchase.

Dramatic discounts on MicroSD cards are pretty common these days, but this particular deal is so good that it's unlikely to be repeated in the near future. Get an order in quickly if you want to claim one.
