Samsung 128GB up to 48MB/s EVO Class 10 – $25 OR LESS @ Walmart (YMMV)

First post, so I apologize if I do something wrong here.
I picked up a couple of these yesterday at my local walmart for $25. Searched for them on Brickseek and there were quite a few available. They were only $20 at a store a bit further.
