Looking for some big deals on big expandable storage? For those in the US, Amazon has some of the lowest prices we've ever seen on Samsung branded MicroSD cards, and no one has to stand outside in the cold to get them. At the time of writing the 128GB EVO MicroSDXC card is just $44.99, a stunning price for a capacity that would have cost $200 or more a few years ago. It's a savings of $53 off the retail price.

If you don't need quite that much storage, the 64GB version of the card is going for just $17.99. A 32GB card will set you back $9.99, and the 16GB version hardly seems worth considering at $6.99. SanDisk cards are also on sale, mostly for the same prices and capacities, though the SanDisk versions go down to 8GB ($5.99) or up to a whopping 200GB ($134.99, $110 off). The SanDisk 128GB card is more expensive at $58.99. Naturally all of them include free two-day shipping for Amazon Prime customers, though I'll point out that shipping services will be slow this time of year.

The SanDisk 128GB card has now dropped to $44.99 which matches Samsung's price for its EVO card mentioned above.

Samsung has dropped the prices of the 128GB card by another $5 from $44.99 to $39.99 and the 64GB card from $17.99 to $16.99. There has never been a better time to buy high capacity MicroSD cards than this Black Friday weekend.

These prices don't appear to be linked to Amazon's rolling Black Friday promotions, but there are so many that we might have missed them. Between the low price and the possibility of limited stock, prospective buyers should get an order in as soon as possible.
