This deal has ended.
Update: this has jumped up $10 in price. Buy.com has the 1TB Fantom Drives G-Force External Hard Drive priced at $119.99 after this $20 mail-in rebate (through 10/31). Shipping is free and there is no sales tax (except CA, MA, MD, TN). $0.12 per gigabyte is a phenomenal deal on external storage, plus it's compatible with either Mac or PC (USB and eSATA) and comes with a one-year warranty.
