Best Buy offers the Western Digital Easystore 4TB USB 3.0 Portable External Hard Drive in Black bundled with a $10 Best Buy gift card and either a $20 Shutterfly gift card, or Shutterfly 8" x 8" Photo Book for $109.99 with free shipping. Assuming you'll use the gift card, that's the lowest price we could find for the hard drive alone by $5, although we saw this same bundle three weeks ago with a $25 Best Buy gift card. It features transfer rates up to 5Gbps.
