PNY Duo-Link On-the-Go 64GB Micro USB/USB 3.0 Convertible Flash Drive for $9.99 shipped. Here is a screenshot for reference. This is somewhat of an unusual USB drive in that it has both USB 3.0 connector as well as Micro USB connector, which should make it easy and fast to transfer data between PC/Mac, tablets, and phones.
This deal has expired as the price has been raised. Congratulations to those able to get in on it.
