Samsung EcoGreen F2 HD103SI 1TB SATA Internal Hard Drive for $69.99 shipped. Here is a screenshot for your reference. Here is more information. This is a 5400rpm drive designed to be energy-efficient instead of maximum speed, which makes it a more appropriate storage drive than a boot drive. Most places have it for about $80.
This deal has expired as the price has been raised. That was fast. Congratulations to those able to get in on it.
