As one of its daily deals, Western Digital Store offers its factory-refurbished Western Digital 4TB My Book USB 3.0 External Hard Drive, model no. WDBFJK0040HBK-NESN, for $109.99 with free shipping. That's tied with our mention of a refurb from December and the lowest total price we've seen. (It's also $23 under the best price we could find for a new unit.) It features local and cloud backup and up to 5GB/s data transfer speeds. Deal ends today.

A 6-month Western Digital warranty applies.
