Microcenter and Walmart has them as well. The 16GB is plenty for most, with a $3 app and a $3 cable, you can READ data off of a USB flash drive (i.e. play movies, music). I didn't know this and got the 32GB...otherwise I would have picked up the 16GB. https://play.google.com/store/apps/details?id=com.homeysoft.nexususb.importer&hl=en
