Amazon has Sony memory cards on sale today and the 128GB and 32GB cards are both great values. Right now you can pick up the 128GB card for $33.50 and just $9 will buy you the 32GB chip. Not a bad price, not bad at all.
Both cards are UHS-1 with up to 70MB/s transfer rates. They aren't the fastest cards on the market, but will work fine for storing media on your phone or tablet. The cards are eligible for free Prime shipping.
I'm reaching for something else to tell you about this deal that is new or original and I'm coming up blank. Memory cards have become so ubiquitous in the mobile arena that they're about as exciting as Ziplock bags. *Sigh* They aren't terribly exciting, but they're cheap and from a reputable brand. Links are below if you want to buy one.
