Walmart offers the Toshiba 1TB Portable USB 3.0 External Hard Drive, model no. PH2100U-1EWR, for $79 plus $2.97 for shipping ($0.08/GB). (Free Site-to-Store is also available.) That's tied with our mention from two weeks ago as the lowest total price we've seen for this model. Sales tax is added where applicable. The enclosed 2.5" hard drive features a 8MB cache and runs at 5400 rpm.
