Western Digital Caviar Black 750GB SATA Internal Hard Drive for $66.95 shipped. Here is a screenshot for your reference. Note that it comes in OEM packaging, which means no pretty retail box and marketing materials but is otherwise identical. The Black Edition is Western Digital’s high-performance product line of SATA drives. Most places have it for $79 or more.
This deal has expired. That was fast. Congratulations to those who were able to get in on it.
