Sorry, this deal is expired.
Update: this is now out of stock in most locations. Office Depot has the 500GB Seagate External Hard Drive, still priced at $89.99. $0.18 per gigabyte is a great deal on external storage, it's compatible with both PC and Mac, and it's only 7.5" tall. Shipping is free, as is in-store pickup, and sales tax is charged in most states.
