As one of its daily deals, Best Buy via eBay offers the SanDisk 64GB Ultra Fit USB 3.0 Flash Drive, model no. SDCZ43-064G-A46, for $14.99. with free shipping. (Walmart has it for a few cents more via in-store pickup.) That's the lowest total price we could find by $7, although last month we saw it for a buck less. It features transfer speeds of up to 130MB/s. Deal ends today.
