When built-in storage just isn't enough, you can always pop in a microSD card. Well, unless you have a Nexus 6... or the new Galaxy S6... or a Moto X... or—okay look, that's not the point. There are still some phones that support microSD cards and here's a 64GB card that's mega-cheap. Alright?

The PNY Turbo Performance 64GB card retails for $50, but is usually listed on Amazon for $35-40. This deal for $25 is a pretty good one, then. It's a class 10 UHS-1 card capable of 90MB/s transfer speeds. It won't be as snappy as internal NAND, but such is the price you pay for removable storage.

If you have Amazon Prime, you can get free 2-day shipping on this card. Smaller versions are also available from Amazon.

Sold Out

It looks like Amazon is sold out. The listing now defaults to a third-party seller offering the card for $45—a decidedly less appealing deal.

The deal is back.
