This deal has ended.
Buy.com has the Iomega Limited Edition 250gb USB External Hard Drive for only $59.95 after a $30 mail-in rebate valid through 6/18. Plus, shipping is free and there is no sales tax (except CA, MA, MD, TN). Also, new customers can use this $5 off $50 coupon or new Google Checkout users can sign up and get a $10 off discount (you can't get both). This is not available for under $100 elsewhere and clocks in at only $0.24 per gigabyte (or $0.20 with Google Checkout), the best I've seen for a brand-name 250gb drive.
