From 9to5Toys.com:

Amazon has the Transcend 64GB Jetflash Retractable USB Flash Drive for $29.99 with free shipping.. That’s the lowest price we’ve ever seen on a 64GB flash drive from a reputable brand/store. The drive reads 19 MByte/s and writes 7 MByte/s and ships in Amazon frustration-free packaging. These deals don’t usually last long.
