Storage is always getting cheaper thanks to the unstoppable march of technology. That's particularly apparent in the prices of microSD cards, which are more affordable than ever. I remember once paying $100 for a 1GB SD card, but that was many years ago. Today, you can get the Silicon Power 128GB microSD card for $29.95.The Amazon listing says it's down from just $31.99, but that's only the most recent stop in a downward trend. Last year, this card was more than twice as expensive, and a few months ago it was over $40. It's now about $10 cheaper than comparable Samsung cards.2016-05-16 13_08_20-Silicon Power 128GB up to 75MB_s MicroSDXC UHS-1 Class10, Elite Flash Memory CarThe Silicon Power card supports UHS-1 speeds and comes with a full SD adapter.

Lightning Deal

This card is on sale for even less, just .90 until 1AM Eastern. It's a lightning deal, so there's a limited stock as well. It's only about 40% gone as of this posting, so you've got a shot. Don't wait too long, though.
