Amazon offers a few gold box deals on  Micro SD memory cards today. There’s not  too many currently shipping smartphones that can take an SD card any more, but the Samsung Galaxy S4 can, and this is a great way to get additional storage on this phone. The 32GB is just under $20.00 and the 64GB is $42.00 for the two popular sizes of micro sd cards for mobile phones. Don’t wait on these deals because these will go fast and only valid today, or while supplies last.
