Walmart offers the SanDisk 64GB Ultra Fit USB 3.0 Flash Drive, model no. SDCZ43-064G-A46, for $13.99. Choose in-store pickup to dodge the $5.97 shipping fee. That's a buck under our mention from two weeks ago and the best price we've seen for a SanDisk 64GB Ultra Fit flash drive. (It's a low now by $2.) It features up to a 130MB/s transfer speed.
