Best Buy offers the Western Digital Easystore 4TB External USB 3.0 Hard Drive bundled with a $25 Best Buy Gift Card for $99.99 with free shipping. Assuming you'll use the gift card, that's $25 below our mention from last week, a savings of $125, and the lowest price we've seen. It features automatic backup and data transfer rates up to 5Gb/s. (It also includes a free Shutterfly photo book or $20 gift voucher.)
