The official Best Buy store via eBay offers the WD 1TB My Passport Ultra USB 3.0 Portable Hard Drive for $49.99 with free shipping or in-store pickup (still available, see update above). That’s 50% below the list price of $100 and one of the best prices we’ve ever seen for any 1TB portable HDD. Amazon is currently selling it for $69.
With ample storage space and fast USB 3.0 transfer speeds, this drive is perfect for Time Machine backups.
