PNY Elite 480gb portable SSD $39 (or as low as $20) B&M Walmart YMMV $39
I was at one of my local wallyworlds and saw a price drop on this portable ssd from 59.99 to 39. There was a lot available and seem many are available at difference walmarts. I put in zipcode 38112 and saw many available. Currently Amazon has it for $59[amazon.com]. I have also given walmart.com link for reference but this in store deal.
